The electric force is the force that exists between two electrically charged objects or particles. The force is either repulsive or attractive depending on whether the objects have the same or opposite charges, respectively. Electric force can be calculated using Coulomb's law.

Alston answered that gravity is a force that is not fundamentally an electric force. This statement is correct because gravity is a fundamental force that acts between two massive objects. It does not depend on electric charges. The force of gravity is always attractive and can be calculated using Newton's law of universal gravitation.

The other fundamental forces in the universe are the strong nuclear force and the weak nuclear force. These forces are responsible for holding the nucleus of an atom together and are not electric in nature.

The distance between your eye and the image of the butterfly in the mirror is: the same as the distance between your eye and the actual butterfly

The distance between your eye and the image of the butterfly in the mirror is the same as the distance between your eye and the actual butterfly, which is the sum of the distance from your eye to the mirror and the distance from the mirror to the butterfly.

To calculate this, we need to measure the distance from your eye to the mirror, which can be done using a ruler or tape measure, and then measure the distance from the mirror to the butterfly, which can be done using a ruler or tape measure as well. Once we have these two measurements, we can simply add them together to get the total distance between your eye and the image of the butterfly in the mirror.

To clarify further, let's use an example. If your eye is 10 cm away from the mirror and the butterfly is 30 cm away from the mirror, then the total distance between your eye and the image of the butterfly in the mirror is 40 cm. This is because 10 cm (from your eye to the mirror) + 30 cm (from the mirror to the butterfly) = 40 cm.

To explain to Jacob how the number of field lines and the magnitude of the charge are related, Imad should mention that the number of field lines is proportional to the magnitude of the charge.

There is a relationship between the number of field lines and the magnitude of the charge. The magnitude of the charge is directly proportional to the number of field lines that pass through the surface that is perpendicular to the field lines. The number of field lines created by a charge or charges is proportional to the charge or charges' magnitude.

In the absence of any other charges or objects, the field lines emanating from a charge with magnitude q will terminate on another charge with magnitude q of opposite polarity, according to Coulomb's law. Therefore, Jacob should be told that the number of field lines is proportional to the magnitude of the charge, meaning that if the charge's magnitude increases, the number of field lines will increase as well.

The rate at which the plane is moving north is 210 mph.

We can use vector addition to solve this problem. Let's denote the speed of the plane with respect to the ground as V, and the speed of the wind as W. We can break down the speed of the plane into two components: one component due north, denoted as Vn, and one component due east, denoted as Ve. Similarly, we can break down the speed of the wind into two components: one component due north, denoted as Wn, and one component due east, denoted as We.

Since the plane is moving directly towards its destination, we know that the component of its velocity due east, Ve, is zero. Therefore:

V = [tex]\sqrt{(Vn^2 + Ve^2) }[/tex]= Vn

We also know that the speed of the wind due north, Wn, is zero (since the wind is blowing from west to east). Therefore:

W = [tex]\sqrt{(Wn^2 + We^2)}[/tex] = We

Now, we can use vector addition to find the speed of the plane due north. The northward component of the plane's velocity is given by:

Vn = V * cos(theta)

where theta is the angle between the velocity vector and the northward direction. Since the plane is moving due north, theta is 0 degrees. Therefore:

Vn = V * cos(0) = V

The northward component of the wind's velocity is given by:

Wn = W * sin(theta)

where theta is the angle between the velocity vector and the northward direction. Since the wind is blowing from west to east, theta is 90 degrees. Therefore:

Wn = W * sin(90) = W

Now, we can add the northward components of the plane's and the wind's velocities to find the northward component of the resultant velocity:

Vn + Wn = V + W * sin(90)

Simplifying this equation, we get:

Vn = V + Wn = V + W * sin(90) = 210 + 0 * sin(90) = 210 mph

A 0.105-kg hockey puck moving at 30 m/s is caught and held by a 61-kg goalie at rest.

The velocity of the goalie is given. In the problem, the momentum of the hockey puck is defined as 0.105 kg x 30 m/s = 3.15 kg*m/s.

The law of conservation of momentum claims that the sum of the momenta of two objects is conserved throughout the collision.

Momentum is always conserved, but the total energy in the system is not (since some energy is lost as sound, heat, and deformation of the objects during a collision).

This is given as the initial momentum of the puck, and since the total momentum of the system is conserved, the momentum of the puck after the collision is zero since the goalie is at rest.

The total momentum of the system is calculated using conservation of momentum principles.

Using the conservation of momentum law, the velocity of the goalie can be calculated, which is given by:

[tex]$$\begin{aligned} 0.105 \text{ kg}\times 30 \text{ m/s} &= (0.105 \text{ kg}+61 \text{ kg}) \times v \\ 3.15 \text{ kg}\cdot \text{m/s} &= 61.105 \text{ kg}\times v \\ \frac{3.15 \text{ kg}\cdot \text{m/s}}{61.105 \text{ kg}} &= v \approx 0.0517 \text{ m/s} \end{aligned}$$.[/tex]

The goalie's velocity is 0.0517 m/s, which is a very modest speed.

The normal-mode wavelengths decrease when the air in an organ pipe is replaced by helium, at the same temperature. This is because helium has a lower molar mass than air, and therefore a lower speed of sound, which causes the normal-mode wavelengths to decrease.

The normal-mode wavelengths are determined by the length of the pipe L and the speed of sound in the pipe

V.λn = 2L/nVn is the index of the mode, which can be any integer.

When helium is used instead of air, the speed of sound in the pipe rises because the mass of the helium molecules is smaller than that of the air molecules, so the gas molecules must travel quicker to achieve the same speed. Because the wavelength of a standing wave must fit into the pipe precisely, the increase in velocity causes the wavelength to decrease. The normal-mode wavelengths will be lowered as a result of this.

The relationship between the index of refraction and the speed of light in a medium is that the higher the index of refraction is: the slower the speed of light in that medium

The index of refraction is a measure of how much a light ray is bent, or refracted, as it enters a material or medium. The amount of refraction increases as the index of refraction increases, which in turn causes light to travel slower in the medium.

The index of refraction is related to the speed of light in the medium because the amount of refraction affects the speed of light in that medium. The index of refraction is a ratio between the speed of light in a vacuum and the speed of light in a medium.

This is calculated as the speed of light in a vacuum (c) divided by the speed of light in the medium (v). This ratio is usually represented as n, and so the formula for the index of refraction is: n = c/v. As the index of refraction increases, the speed of light in the medium decreases.

In a medium with a low index of refraction, the speed of light is higher than in a medium with a higher index of refraction. This is because a low index of refraction means that the light ray is not being refracted very much, so it is able to travel faster.

A higher index of refraction means that the light ray is being refracted more, so it is forced to travel slower. This explains the relationship between the index of refraction and the speed of light in a medium; the higher the index of refraction, the slower the speed of light in that medium.

The electric motor's efficiency is 51.06%.

The majority of electric motors are made to operate between 50% and 100% of rated load. Typically, maximum efficiency is within 75% of rated load. Hence, the allowable load range for a 10-horsepower (hp) motor is between 5 and 10 hp; its peak efficiency is at 7.5 hp. Below roughly 50% load, a motor's efficiency tends to decline significantly.

To calculate the effort required to raise the object, use the formula:

Work = Force x Distance

= m x g x h (where m is the mass of the object, g is the acceleration due to gravity, and h is the height lifted)

= 34 kg x 9.81 m/s² x 11 m

= 3,769.34 J

The energy consumed by the electric motor is given as 7.4 kJ.

Therefore, the input power is:

Input power = Energy consumed / time taken

= 7.4 kJ / t

Efficiency=(Output power/Input power) x 100%

Output power = Work done/time taken

= 3,769.34 J / t

As a result, the electric motor's efficiency is:

time of flight = 0.5533 seconds

horizontal range = 1.107 metres

final velocity is 5.779 m/s at 70° downwards

Step-by-Step Solution

initial horizontal velocity (ux) = 2.0 m/s

initial vertical velocity (uy) = 0

vertical displacement (sy) = -1.5 m

neglecting air friction (drag), acceleration due to gravity (g) in the vertical component, is constant (9.8 m/s²), and horizontal velocity is ALWAYS constant. i.e, acceleration=0. Now using the equations of motion for the x-component:

[tex]s=ut\\v^2=u^2\\v=u[/tex]

for the y-component:

[tex]v=u-gt\\v^2=u^2-2gs\\s=ut-\frac{1}{2}gt^2\\[/tex]

(a) the time the marble will take to reach the floor.

using an equation that we have all the data for,

[tex]s=ut-\frac{1}{2}gt^2[/tex]

-1.5 = 0 - 1/2(9.8)×t². Solving this to get t,

∴ time of flight = 0.5533 seconds

(b) the distance of the table that the marble will land.

similar to the previous question, we can use one of the equations of motion again, but this time, there's only one equation we can use:

[tex]s=ut[/tex]

s = 2×0.5533

∴ horizontal range = 1.107 metres

c. the velocity of the marble just before it reaches the floor.

For this, we require both the x and y components of final velocity, and then we can calculate the resultant vector of the two velocities, as well as the direction/angle. Since u=v in x-component, we already have Vx. To find Vy, we can use:

[tex]v=u-gt[/tex]

v = 0 - 9.8×0.5533

∴ final vertical velocity = -5.4223 m/s

Therefore, final velocity = [tex]\sqrt{Vx^2+Vy^2}[/tex]

v = √(2.0² + (-5.4223)²) = 5.779 m/s

To find direction of velocity, tan∅ = Vy/Vx

∅ = tan⁻¹(5.4223/2.0) = 70°

Therefore, final velocity is 5.779 m/s at 70° downwards

This phenomenon is known as refraction, and is caused by the difference in speed between light passing through the two different materials. The light ray will slow down when passing through water, so it will bend closer to the normal.

When a light ray enters the air from water, the light ray will refract closer to the normal. This is due to the fact that light travels faster through air than through water, so when the light enters the air, it bends towards the normal. The amount of refraction is determined by the index of refraction of each material. Since the index of refraction of air is lower than the index of refraction of water, the light ray will bend closer to the normal.

To better understand this, imagine a light ray traveling from a denser material (like water) to a less dense material (like air). As the light ray enters the air, the speed of the light increases, causing it to bend closer to the normal. This is due to the law of refraction, which states that the angle of refraction is inversely proportional to the speed of the light ray. In summary, when a light ray enters the air from water, it will refract closer to the normal. This is due to the fact that light travels faster through air than through water, so the light ray bends towards the normal. The amount of refraction is determined by the index of refraction of each material, with the lower index refraction material (air) resulting in the light ray bending closer to the normal.

The automobile will travel for 300 m during that time. The result is obtained by using the formula for uniformly accelerated motion.

The equations apply in uniformly accelerated motion in horizontal dimension are

v₁ = v₀ + at

v₁² = v₀² + 2ax

x = v₀t + ½ at²

Where

We have

Find the distance that the automobile travel during that time!

From that information, we can find the acceleration.

a = (v₁ - v₀)/t

a = (40 - 20)/10

a = 2 m/s²

The distance will be

x = v₀t + ½ at²

x = 20(10) + ½ (2)(10)²

x = 200 + 100

x = 300 m

Hence, that time the automobile will reach the distance of 300 m.

The density of the hypothetical planet, in kg/m3, is 6,246 kg/m3

V = (4/3)πr3

V = (4/3)π(162 x 106 m)3

V = 9.30 x 1018 m3

The density of the planet in kg/m3

We know that Density is given as

D = Mass ÷ Volume

D = 1027 kg ÷ 9.30 x 1018 m3

D = 6,246 kg/m3

Density is a measure of mass per unit of volume. It is expressed in terms of mass per volume and is typically measured in kg/m3 or g/cm3. Density is an important physical property of matter as it allows us to compare the mass of different substances at the same volume.
