Answer:

in addition infrared thermometers don't measure metal surfaces particularly well anyway (metals typically have a low emissivity). Measuring electrical resistance is better.

The type of microscope that has the highest resolution and can resolve objects less than 1 angstrom apart is the Transmission electron microscope (TEM).

What is a microscope?

A microscope is an instrument that allows scientists and medical experts to examine microscopic organisms and objects. They are used in a variety of scientific and medical fields to investigate the behavior of cells and other microscopic organisms. Scientists also use microscopes to study the surface of materials, such as metals or plastics, in order to understand how they are made and how they behave.

There are several types of microscopes, each with its own set of advantages and disadvantages. The highest resolution and the most powerful microscopes are the electron microscopes. The electron microscope utilizes electrons instead of light to create an image.

They use an electron beam to create a magnified image of a sample. The transmission electron microscope (TEM) is the most powerful type of electron microscope. They use an electron beam to send electrons through a thin section of a sample, which creates a magnified image of the sample on a screen.

The resolution of the TEM is extremely high, allowing scientists to study the sample's internal structure in great detail. As a result, it is capable of detecting objects that are less than one angstrom apart. The atomic structure of materials can also be viewed using this type of microscope.

The mass, in units of me (the mass of the earth), of a planet with twice the radius of the earth for which the escape speed is twice that of the earth is 8 me.

The amount of matter in an object is referred to as mass. Mass is expressed in terms of the unit kilogram in the International System of Units (SI).

The escape velocity is defined as the minimum velocity required for an object to leave the gravitational influence of another object. For example, if a ball is thrown from the surface of the earth at a speed of 11.2 km/s (40,320 km/h), it will escape the earth's gravitational pull and continue into space.

The formula for escape velocity is given by:

  v=√(2GM/r)

Where, v is the escape velocity, G is the gravitational constant, M is the mass of the planet, and r is the radius of the planet.

The formula for mass:

  m = v²r/Gm = (2v)²(2r)/GMm = 8r/G

The voltage is V = I × R = 5 ohms.

The voltage across a 5 ohm resistor when the switch has been in position a for a long time is determined by Ohm’s Law.

This law states that the voltage (V) across a resistor is equal to the current (I) through it multiplied by the resistance (R). Therefore, the voltage across the 5 ohm resistor is V = I × R = 5 ohms.

This voltage can also be found by considering the flow of electrons. In a circuit with a battery and a switch, electrons flow from the positive terminal of the battery to the negative terminal.

When the switch is in position a, the 5 ohm resistor is in the path of the electrons and acts as a barrier.

This resistance causes the electrons to slow down and the voltage across the resistor is determined by the amount of this resistance.

Charge that exists in a body that has fewer electrons than protons is known as positive electrons.

a. To find the electric field at the origin due to charge Q1, we can use the formula for the electric field due to point charge:

$$E_1 = \frac{k Q_1}{r_1²}$$

k is Coulomb constant (k = 9.0 × 10⁹ N m²/C²), Q1 is the charge, and r1 is the distance from the charge to the point where we want to find the electric field.

Q1 = 2.6 μC and r1 = 3.0 m (since x1 = -3.0 m is the distance from Q1 to the origin).

$$E_1 = \frac{(9.0 \times 10⁹ N m^2/C²)(2.6 \times 10⁻⁶C)}{(3.0 m)²} \approx 7.80 \times 10⁵ N/C$$

The electric field is directed away from point charge, so direction of the electric field at the origin due to Q1 is to the right (positive x direction).

b. Similarly, to find the electric field at the origin due to charge Q2, we use the same formula:

$$E_2 = \frac{k Q_2}{r_2²}$$

where Q2 = 1.4 μC and r2 = 4.0 m (since x2 = 4.0 m is the distance from Q2 to the origin).

$$E_2 = \frac{(9.0 \times 10⁹ N m²/C²)(1.4 \times 10⁻⁶ C)}{(4.0 m)²} \approx 3.94 \times 10⁵ N/C$$

The electric field is directed towards point charge, so direction of the electric field at the origin due to Q2 is to the left.

c. $$\vec{E} = \vec{E_1} + \vec{E_2}$$

$\vec{E_1}$ is the electric field due to Q1 and $\vec{E_2}$ is the electric field due to Q2.

To determine the total power delivered to the circuit (i.e., the total power dissipated in the resistors), you can use the formula:

P = I²R ; where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.

To find the current, you can use Ohm's law:

V = IR

where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms.

Here's an example:

Suppose you have a circuit with two resistors, R1 and R2, connected in series.

The voltage across the circuit is 10 volts, and the resistances of the two resistors are 2 ohms and 4 ohms, respectively. You can find the total resistance of the circuit by adding the resistances of the two resistors:

R = R1 + R2 = 2 + 4 = 6 ohms

To find the current in the circuit, you can use Ohm's law:

I = V/R = 10/6 = 1.67 amps

Then, you can find the power dissipated in each resistor:

P1 = I²R1 = (1.67)²(2) = 5.56 wattsP2 = I²R2 = (1.67)²(4) = 11.11 watts

And finally, you can find the total power dissipated in the circuit by adding the power dissipated in each resistor:Ptotal = P1 + P2 = 5.56 + 11.11 = 16.67 watts

Jumping off a floating canoe towards a dock may not be as simple as it appears due to the reaction force created by the canoe's displacement of water. Therefore, it's important to exercise caution and consider the various factors that could impact the jump's outcome. This phenomenon is known as the "reaction force," which is equal and opposite to the force exerted by the canoe on the water.

When you jump off the canoe, you create a force that pushes you forward towards the dock, but the water's reaction force pushes you backward, causing you to fall into the water instead. When you jump from the front of a floating canoe towards a dock, you might expect to land on the dock effortlessly.

Moreover, the instability of the canoe on the water surface, the angle and velocity at which you jump, the distance between the canoe and the dock, and the depth of the water could all affect the outcome of your jump.

Given, Mars has a mass of about 0.1075 times the mass of Earth and a diameter of about 0.533 times the diameter of Earth.

To find the acceleration of a body falling near the surface of Mars, we can use the formula:

g = GM/r²

where: g = acceleration due to gravity on Mars

M = mass of Mars

r = radius of Mars

We know that mass is proportional to the cube of the radius. So we can say:

Mars/Mass of Earth = (radius of Mars / radius of Earth)³0.1075M/ME

                                = (0.533RE/RE)³0.1075

                                = 0.01514ME

Simplifying this equation, we can say:

M = 0.1075 × MEr = 0.533 × RE

Now, let's calculate the acceleration due to gravity on Mars:

g = GM/r²g

Given resistance values of 200 Ω, 250 Ω, and 1000 Ω are connected in parallel across a source. The source current is 6 A. We are required to find the current that flows through the 200 Ω resistor.

Recall that when resistors are connected in parallel, the current is divided among them. And the voltage across each resistor is the same. The equivalent resistance of three parallel resistors is given by;

1/Rp = 1/R1 + 1/R2 + 1/R3Rp = (R1 x R2 x R3)/(R1R2 + R1R3 + R2R3)

Put the values into the formula;

Rp = (200 x 250 x 1000)/(200×250 + 200×1000 + 250×1000)

Rp = 52.17 Ω

The total current in the circuit, It = 6 A

From Ohm's Law;

V = IR,

where V is the voltage across each resistor

V1 = V2 = V3V = I×R

Therefore; V = I×Rp

The current flowing through the 200 Ω resistor, I1 = V1/200 = I × Rp/200The current flowing through the 200 Ω resistor, I1 = (6×52.17)/200I1 = 1.56 A

In this issue, we can utilize preservation of energy to track down the last speed and course of Jeff's crash mobile after the impact with Julia's. Before the impact, the energy in the x-heading is zero, and in the y-course, it is 60 kg × 4 m/s = 240 kg⋅m/s north. Julia's force is 45 kg × 6 m/s = 270 kg⋅m/s west.After the crash, the energy in the x-course is rationed. The absolute energy in the x-course is as yet zero, as Julia's force that way is likewise zero. In the y-heading, the absolute force after the crash is 60 kg × vj + 45 kg × 2 m/s sin 15°, where vj is Jeff's last speed in the y-course.Utilizing protection of energy, we can compare the force when the crash in the y-heading:

60 kg × 4 m/s + 45 kg × 6 m/s = 60 kg × vj + 45 kg × 2 m/s sin 15°

Working on this situation, we get:

240 kg⋅m/s + 270 kg⋅m/s = 60 kg × vj + 12.19 kg⋅m/s

Addressing for vj, we get:

vj = (240 kg⋅m/s + 270 kg⋅m/s - 12.19 kg⋅m/s)/60 kg

vj = 7.133 m/s south

Consequently, Jeff's last speed is 7.133 m/s south. To find the course, we can utilize geometry. The point of Jeff's last speed concerning the x-pivot is given by:

θ = tan^-1(vj/4 m/s)

The frequency of a standing wave with a wave speed of 12 m/s as it travels on a 4.0-m string fixed at both ends is 3.0 Hz.

A standing wave is produced by a wave with the same amplitude, frequency, and wavelength moving in the opposite direction with the initial wave. This indicates that the wave appears to stand in one place. Standing waves can only be generated in a medium if there is a boundary that restricts the movement of the wave. Standing waves can be observed in various shapes and sizes, and their frequencies are determined by a variety of factors, including the wave speed and the length of the string. When a standing wave is generated in a string, the points where the wave appears to be fixed are known as nodes, while the points where the string vibrates with the most amplitude are known as antinodes.In this scenario, the wave speed and the length of the string are given.

The wave speed, frequency, and wavelength of a wave are related by the formula v = fλ, where v is the wave speed, f is the frequency, and λ is the wavelength. Since the length of the string is fixed, the wavelength of the standing wave is twice the length of the string. Thus, λ = 2L = 8 m. Plugging in the values for the wave speed and wavelength, the frequency can be calculated as follows:f = v / λ = 12 m/s / 8 m = 1.5 Hz.

In this case, the force of 90 N is applied perpendicular to the end of a wrench that is 0.5 m long. Assuming the force is applied at the end of the wrench, the distance from the pivot point to the point of application of the force is 0.5 m. Since the force is perpendicular to the wrench.

The angle between the force vector and the vector from the pivot point to the point of application of the force is 90 degrees. Using the formula for torque, the torque produced by the force is: Torque = force x distance x sin(angle)

Torque = 90 N x 0.5 m x sin(90)Torque = 45 Nm

The longest possible wavelength for a standing wave on a string is: the length of the string itself

This is because, in order to create a standing wave, two traveling waves must interfere with one another and create a wave pattern that is fixed in space.

As the wavelength of the traveling waves increases, the nodes (points of zero displacements) of the standing wave become closer together. Therefore, if the wavelength is equal to the length of the string, the nodes of the standing wave are located at the two ends of the string and the wave pattern remains stationary.

This means that any longer wavelength traveling wave would not be able to interfere and form a standing wave on the string.

The pole vaulter gains potential energy during the ascent phase of the vault as he gains altitude. When he reaches the highest point, he has the maximum potential energy. During the descent phase of the vault, the potential energy is converted into kinetic energy.

Based on this principle, we can use the conservation of energy equation to find the time taken by Bubka to return to the ground. The equation for conservation of energy is given as: Potential energy (P.E) = Kinetic energy (K.E)

P.E = mgh where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the ground.

K.E = 1/2 mv² where v is the velocity of the object.

The velocity of Bubka when he reached the highest point can be assumed to be zero since he had to come to a stop before starting his descent. Therefore, the initial kinetic energy is zero.

P.E at the highest point = K.E at the lowest point

Let t be the time taken by Bubka to return to the ground. We can assume that Bubka moves with uniform acceleration. Using the kinematic equation, we have: v = u + at where u is the initial velocity and a is the acceleration.

When Bubka reaches the ground, his final velocity is zero.

Therefore, we have: v = 0u = at

Substituting the value of u in the equation for K.E, we have: K.E = 1/2 mv² = 1/2 ma²t²

Substituting the value of P.E and K.E in the equation for conservation of energy, we have:

mgh = 1/2 ma²t²

Simplifying, we get: t = sqrt(2h/g)

Substituting the values of h and g, we have:

t = sqrt(2 x 6.10 / 9.81)t = sqrt(1.240)t = 1.11 seconds

Therefore, it took Bubka 1.11 seconds to return to the ground from the highest part of his vault.

The force generated per unit field strength on a 20.0 cm wide section of the loop with a current of 5.5 A is: 0.001 newtons per tesla

The force generated per unit field strength on a 20.0 cm wide section of the loop with a current of 5.5 A is given by the formula F = (μI) / 2πr,

where μ is the permeability of free space, (4π x 10-7 N/A²)

I is current, and r is the radius of the loop.

In this case, the force is (4π x 10-7 x 5.5) / (2π x 0.1) = 0.001 N/T.

In other words, the force generated per unit field strength on a 20.0 cm wide section of the loop with a current of 5.5 A is 0.001 newtons per tesla.

The formula for the force generated per unit field strength on a loop is derived from the fact that the force is a result of the magnetic field generated by the current flowing in the loop.

The magnitude of the magnetic field generated is proportional to the current and inversely proportional to the radius of the loop. Since the force is a product of the current and the magnetic field, it is proportional to the square of the current and inversely proportional to the square of the radius of the loop.

In summary, the force generated per unit field strength on a 20.0 cm wide section of the loop with a current of 5.5 A is 0.001 newtons per tesla, given by the formula F = (μI) / 2πr, where μ is the permeability of free space (4π x 10-7 N/A²), I is current, and r is the radius of the loop.

The resistence of each resistor can be calculated by using the equation for resistors in series: R = Ps/I and the equation for resistors in parallel: R = Pp/I.

By substituting the given values for Ps, I and Pp into the equations, we get R1 = Ps/I and R2 = Pp/I. Thus, the value of each resistor can be determined by dividing the total power by the total current.

These equations are based on Ohm's law, which states that the voltage across a resistor is equal to the current through the resistor multiplied by the resistance. By connecting resistors in series or parallel, the overall resistance of the network can be calculated. Knowing the total power and total current, the individual resistances of each resistor can be determined.

The resistance of a wire is inversely proportional to the cross-sectional area of the wire. So, the resistance of the second wire is one-half of the resistance of the first wire, which is 100 ohms.

Resistance of a copper wire with a cross-sectional area and length.The resistance of a copper wire with a cross-sectional area and length can be calculated using the formula:R=ρL/A

Substituting the given values of resistance R and cross-sectional area A for the first copper wire, we get:R₁ = ρL/A ... (1)where ρ is the resistivity of copper, L is the length of the wire and A is the cross-sectional area of the wire.The resistance of the second copper wire with twice the cross-sectional area A but the same length L can be calculated using the same formula as:R₂ = ρL/2A = (1/2)(ρL/A) ... (2)

Substituting the value of R₁ from equation (1) in equation (2), we get:R₂ = (1/2)(R₁) = 1/2 x 200 = 100Ω

Therefore, the resistance of the second copper wire would be 100 ohms.
