The external forces acting on this system are: gravity and the tension in the string.

An Atwood machine is a system consisting of two masses, m, and m, connected by a string that passes over a pulley. In this system, the external forces are gravity and the tension in the string. Gravity pulls both masses downward, while the tension in the string acts in opposite directions on the two masses, pulling the heavier one down and the lighter one up.

The tension in the string is determined by the masses m and m and the acceleration of the system. If m is the heavier mass and m is the lighter mass, the tension in the string will be greater than if both masses had the same weight. This is because the tension must balance the gravitational forces on the two masses. The greater the mass, the greater the gravitational force, and the greater the tension in the string must be to balance it.

The acceleration of the system is determined by the masses, the tension in the string, and the amount of friction in the system. The greater the tension, the greater the acceleration, and the smaller the mass, the greater the acceleration. Friction acts against the acceleration, reducing the net acceleration of the system.

In summary, the external forces acting on an Atwood machine with two different masses m and m are gravity and the tension in the string. The tension in the string is determined by the masses and the acceleration of the system, while the acceleration is determined by the masses, the tension in the string, and the amount of friction in the system.

Explanation:

Nonmetals tend to gain electrons and become anions. For example, in Fig. 2.22 A, a neutral oxygen atom (O), with eight protons and eight electrons, gains two electrons. This gives it two more negative charges than positive charges and an overall charge of 2–.

c) The rubber band is stretched under a constant tension. when you warm the rubber band under the constant tension it will expand instead of shrinking.

If you warm the rubber band while keeping it under constant tension, it will expand instead of shrinking. This occurs due to the fact that the rubber band's atoms begin to vibrate more as a result of the heat. This vibrating motion produces more space between the atoms, causing the rubber band to expand.

The original condition of the rubber band under constant tension is when a rubber band is stretched, it has an intrinsic tendency to restore its original size and shape when the tension is released. It implies that if the rubber band is heated, it will also restore its original size and shape once the tension is released. It will take the same size as it had before being stretched.

The voltage across the inductor during the period when the current changes at 9.1 A/ms with an inductance of 26 mH is 236.6 V.

An inductor is an electrical component that stores energy in a magnetic field when a current passes through it. An inductor is a device that opposes any change in the current flowing through it. The inductor is represented by the symbol L and is measured in henries (H).

The difference in electrical potential between two points in a circuit is known as voltage. The unit of voltage is volts (V).

The voltage across an inductor can be calculated using the formula:

[tex]v = L(di/dt)[/tex]

where v is the voltage, L is the inductance, and [tex]di/dt[/tex] is the rate of change of current.

Substituting the given values, we get:

[tex]v = 26\  mH \times (9.1 \ A/ms)[/tex]

Note that the units for inductance and rate of change of current must be consistent, so we convert the inductance to henries (H) and the rate of change of current to amps per second (A/s):

[tex]v = 0.026\  H \times (9100 \ A/s)[/tex]

[tex]v = 236.6 \ V[/tex]

The total entropy change during this process is, -16.4 J/°C.

To determine the total entropy change during this process, we need to consider both the entropy change of the iron block and the entropy change of the water in the tank. We can assume that the entire process is adiabatic (i.e., no heat transfer occurs between the system and the surroundings), so the total entropy change of the system is zero.

The entropy change of the iron block can be calculated as,

ΔS_iron = m × Cp_iron × ln(T_f / T_i)

where m is the mass of the iron block, Cp_iron is the specific heat capacity of iron, T_f is the final temperature of the iron block, and T_i is the initial temperature of the iron block.

Assuming that the final temperature of the iron block is the same as the temperature of the water in the tank (i.e., 18°C), we can calculate the entropy change of the iron block as,

ΔS_iron = 25 kg × 0.45 J/g°C × ln(18°C / 350°C)

≈ -16.4 J/°C

The entropy change of the water in the tank can be calculated as,

ΔS_water = m × Cp_water × ln(T_f / T_i)

where m is the mass of the water in the tank, Cp_water is the specific heat capacity of water, T_f is the final temperature of the water, and T_i is the initial temperature of the water.

Assuming that the iron block and the water reach a final temperature of 18°C, we can calculate the entropy change of the water as,

ΔS_water = 100 kg × 4.18 J/g°C × ln(18°C / 18°C)

= 0 J/°C

Therefore, the total entropy change during this process is,

Complete Question: -

A force of 7 pounds is required to hold a spring stretched 0.4 feet beyond its natural length. How much work (in foot-pounds) is done in stretching the spring from its natural length to 0.7 feet beyond its natural length?

The final answer are work required to compress the spring from 12 cm to 10 cm is 19.6 J.

The spring's energy and the work it does are both proportional to the amount it stretches or compresses. According to Hooke's Law, the force needed to stretch or compress a spring is proportional to the amount it is stretched or compressed.

Given the spring constant and the total energy stored in the spring, one may figure out how much energy is necessary to compress the spring from a particular point to another using this method. What is the work required to compress the spring from 12 cm to 10 cm?

The work required to compress the spring from 12 cm to 10 cm is calculated using the following formula; W=1/2 k (x_2^2 - x_1^2) where W is the work done by the spring ,k is the spring constant,x1 is the initial position, andx2 is the final position.

Determine the spring constant using the formula, F=kx k=\frac{F}{x}k=\frac{mg}{x} k=\frac{30*9.8}{0.15} k=1960\ N/m Since the spring is being compressed, the value of x2 is smaller than x1.

To find the value of work done by the spring when compressed from x1 to x2, the difference between the potential energies corresponding to these positions is taken.

Thus, the work done by the spring is: W=1/2 k (x_2^2 - x_1^2) W=1/2 (1960) (0.12^2 - 0.10^2) W=19.6\ J

Thus, the work required to compress the spring from 12 cm to 10 cm is 19.6 J.

The natural length of the spring is therefore 12.97 cm.

The natural length of the spring is found by calculating the spring constant using the Hooke's law formula. Spring constant (k) = Force (F) / extension (x). The natural length of the spring refers to the length of the spring when it is not carrying any load. Hooke's law states that the force required to extend or compress a spring by a distance x is proportional to that distance. Mathematically, F=kx, where F is the force applied, x is the displacement from the equilibrium position, and k is the spring constant. To find the natural length of the spring, we need to calculate the spring constant.

To do this, we use the data given in the problem. A load of 12 kg stretches the spring to a total length of 15 cm. We can find the force applied by multiplying the load by the acceleration due to gravity (g), which is 9.8 m/s^2. Thus, F = mg = 12 * 9.8 = 117.6 N. The extension of the spring is given as x = 15 cm - x0, where x0 is the natural length of the spring. Thus, x = 0.15 m - x0. Substituting these values into Hooke's law, we get: k = F/x = 117.6/(0.15 - x0)

Similarly, when a load of 30 kg stretches the spring to a length of 18 cm, we can find the force applied as F = mg = 30 * 9.8 = 294 N. The extension is given as x = 0.18 m - x0. Substituting these values into Hooke's law, we get: k = F/x = 294/(0.18 - x0)

Now we have two equations for k, so we can set them equal to each other: 117.6/(0.15 - x0) = 294/(0.18 - x0) Cross-multiplying and simplifying, we get: 117.6(0.18 - x0) = 294(0.15 - x0) 21.168 - 117.6x0 = 44.1 - 294x0 176.4x0 = 22.932 x0 = 0.1297 m

Explanation:

The odor of trash is due to the presence of particles emitted by decomposing organic matter. During the summer months, the increased temperature causes particles to move faster and collide with each other more frequently. This results in the particles spreading out further, and the odor from the trash becoming more noticeable.

The kinetic energy of the particles in the trash increases with higher temperatures, which means that they move faster and are more likely to escape from the garbage can into the surrounding air. The heat from the sun also speeds up the process of decomposition, leading to the release of more particles and the generation of a stronger odor.

In contrast, during the winter months, the lower temperatures cause the particles to move more slowly, and they collide with each other less frequently. This results in the particles staying closer to the source and the odor from the trash being less noticeable.

In summary, particle energy plays a crucial role in the smell of trash. The higher the temperature, the more kinetic energy the particles have, which leads to faster movement and more frequent collisions. This results in the particles spreading further and generating a stronger odor. Conversely, lower temperatures slow down particle movement, leading to fewer collisions and less noticeable odor.

Answer:

Particle energy play a role in smell because during the summer, the sun's rays are more powerful and can break down more molecules in the air, leading to a stronger smell. In the winter, the sun's rays are weaker and can't break down as many molecules, leading to a weaker smell.

We can also use Newton's second law, which relates the net force on an object to its acceleration:

F = ma

where F is the net force acting on the boat,

m is its mass, and

a is its acceleration.

To calculate the net force, we need to add up the individual forces exerted by Jack and Jill:

F= Fjack+ Fjill

where Fjack is the force exerted by Jack, and Fjill is the force exerted by Jill.

The net force can be calculated as:

F = <-440, 0, 220> + <150, 0, 300>

  = <-290, 0, 520> N

Second, The boat's acceleration can be calculated using Newton's second law:

F= ma

a = F / m

a = <-290, 0, 520>  / 3200

a = <-0.0906, 0, 0.1625> m/s^2

Third, The boat's final velocity can be calculated using its initial velocity, its acceleration, and the displacement:

vf^2 = vi^2 + 2ad

where vi is the initial velocity,

a is the acceleration,

d is the displacement, and

vf is the final velocity.

The displacement can be calculated as:

d = |<6, 0, 1>  - <2, 0, 3>

  = |<4, 0, -2>

  = sqrt(4^2 + 0^2 + (-2)^2)

  = 4.47 m

Plugging in the values, we get:

vf^2 = (1.6 )^2 + 2 * (-0.0906 ) * 4.47

= 1.89

= 1.37 m/s

Therefore, the final speed of the boat is 1.37 m/s.

Fourth, To calculate the work done by Jack, we can use the formula:

W = F * d

where F is the force exerted by Jack, and

d is the displacement of the boat.

Plugging in the values:

W = <-440, 0, 220>  * 4.47

The volume of a cube changes when you increase the length of the side from 1 cm to 2 cm, to 3 cm, and then to 4 cm. A cube is a three-dimensional shape with six identical square faces. When all the faces of a cube are equal in length, it is referred to as a square cube.

Each edge of a cube is the same length, so we can figure out the volume of a cube by multiplying the length, width, and height together.

The volume of a cube is given by V = s^3, where s is the length of one edge of the cube. The volume changes as the length of the side changes. Here's how it changes as the side length increases from 1 cm to 4 cm:

When s = 1 cm, V = 1^3 = 1 cm³
When s = 2 cm, V = 2^3 = 8 cm³
When s = 3 cm, V = 3^3 = 27 cm³
When s = 4 cm, V = 4^3 = 64 cm³

We can see that as the length of the side of the cube increases, the volume increases rapidly. The volume of the cube grows much faster than the length of one of its sides. For example, when the length of the side changes from 1 cm to 2 cm, the volume increases by a factor of 8.

When the length of the side changes from 2 cm to 3 cm, the volume increases by a factor of 3.375 (27 divided by 8). And when the length of the side changes from 3 cm to 4 cm, the volume increases by a factor of 2.37 (64 divided by 27).

The difference in electric potential between two places is known as voltage, often referred to as electric pressure, electric tension, or (electric) potential difference. It translates into the amount of work required to move a test charge between two points in a static electric field. Volt is the name of the voltage-derived unit in the International System of Units.

A capacitor, for example, or an electromotive force can build up electric charge and increase the voltage between two places (e.g., electromagnetic induction in generator, inductors, and transformers).

Electrochemical reactions (such as those in batteries and cells), the pressure-induced piezoelectric effect, and the thermoelectric effect can all produce potential differences on a macroscopic level.

To calculate the time it takes for the voltage across the resistor to reach 10.0V after the switch is closed, you can use the formula

t = RC,

where R is the resistance in Ohms and C is the capacitance in Farads.

Using the given values, the time it will take to reach 10.0V is

t = 10 Ω * 0.05F

= 0.5 seconds.

Therefore, the time it takes for the voltage across the resistor to reach 10.0 v after the switch is closed is 0.5 s.

The region in which it is possible to change the phase of x by raising or lowering the temperature is: phase transition region.

This region is typically marked by an increase in pressure and a decrease in temperature. Temperature and pressure are inversely proportional to one another within this region, meaning that as pressure increases, temperature decreases and vice versa.

The exact temperature and pressure at which the phase transition occurs depends on the type of material being transitioned and its individual characteristics. For example, water boils at 100°C and 1 atm of pressure while other substances may have different boiling points.
