Answer:

Temperature or thermal energy.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, the temperature or thermal energy of matter depends on how much the particles are moving, which depends on the amount of kinetic energy the particles possess.​

Answer: The minimum distance needed from the slits to the screen is approximately 2.46 meters when a He-Ne laser (λ = 633 nm) is used.

Explanation: The distance between successive bright fringes in a double-slit interference pattern is given by the equation:

d(sinθ) = mλ

where d is the distance between the slits, θ is the angle between the line connecting the center of the two slits and the line connecting a point on the screen to the center of the slits, m is an integer representing the order of the bright fringe, and λ is the wavelength of the light.

To find the minimum distance from the slits to the screen that will produce a fringe spacing of at least 1.25 cm, we can use the equation for the first-order bright fringe:

d(sinθ) = λ

where m = 1.

We can solve this equation for sinθ:

sinθ = λ/d

Substituting the values we were given, we get:

sinθ = (633 nm) / (0.250 mm) = 0.002532

Now we can use the small-angle approximation, which states that sinθ ≈ θ for small angles, to find the angle θ:

θ ≈ sinθ = 0.002532

Finally, we can use the following formula to find the distance from the slits to the screen:

y = L*tanθ

where y is the distance from the central maximum to the first-order bright fringe, L is the distance from the slits to the screen, and θ is the angle we just found.

Since we want the distance between successive bright fringes to be at least 1.25 cm, we can set y equal to 1.25 cm and solve for L:

L = y/tanθ = (1.25 cm) / tan(0.002532) ≈ 2.46 m

Therefore, the minimum distance needed from the slits to the screen is approximately 2.46 meters when a He-Ne laser (λ = 633 nm) is used.

Answer:

An incandescent bulb use electrical energy

Explanation:

A force of 680 N is required to get the clock moving, so the maximum static friction is also f ˢ = 680 N. The clock is at rest, so the net vertical force acting on it is 0, and by Newton's second law,

n - mg = 0

where

n = magnitude of the normal force

m = 85 kg = mass of the clock

g = 9.8 m/s² = magnitude of the acceleration due to gravity

So we have

n = mg = (85 kg) (9.8 m/s²) = 833 N

which means the static friction f ˢ is such that

f ˢ = µ ˢ n

Solving for the coefficient of static friction gives

µ ˢ = (680 N) / (833 N) ≈ 0.82

After it starts moving, a force of 540 N is required to keep the clock going at a constant speed, so the kinetic friction is also f ᵏ = 540 N. Then

f ᵏ = µ ᵏ n

and solving for the coefficient of kinetic friction yields

µ ᵏ = (540 N) / (833 N) ≈ 0.65

A vertical air current that is generated by temperature-induced density differences is an example of heat transfer by:

E. convection.

Convection is a mode of heat transfer that involves the movement of a fluid (liquid or gas) due to temperature differences within the fluid. When there is a temperature gradient in a fluid, the warmer and less dense regions rise while the cooler and denser regions sink. This motion of the fluid transfers heat energy from one location to another.

In the given scenario, the vertical air current is generated by the temperature-induced density differences in the air. As the air near the heat source becomes warmer, it becomes less dense and rises, creating an upward current. This process is an example of convection because heat is transferred through the movement of the fluid (in this case, air) itself.

Convection is a common mode of heat transfer in many natural and engineered systems, such as the circulation of air in a room due to a heating system or the movement of water in a pot while being heated.

A vertical air current that is generated by temperature-induced density differences exemplifies heat transfer by convection. In this process, heat energy is transferred through the motion of the fluid (air) as warmer, less dense air rises and cooler, denser air sinks.

Answer:

The wavelength of the wave would increase to 10 meters.

Explanation:

We can use the formula:

velocity = frequency × wavelength

to relate the velocity, frequency, and wavelength of a wave.

Given that the wave has a speed of 20 m/s and a wavelength of 5 meters, we can solve for its frequency as follows:

frequency = velocity ÷ wavelength = 20 m/s ÷ 5 meters = 4 Hz

Now, if the same wave is created in the same medium, but with half the original frequency, its new frequency will be:

new frequency = 4 Hz ÷ 2 = 2 Hz

To find the new wavelength of the wave, we can rearrange the formula above to solve for wavelength:

wavelength = velocity ÷ frequency

Using the new frequency of 2 Hz, we get:

new wavelength = 20 m/s ÷ 2 Hz = 10 meters

Therefore, if the same wave was created in the same medium, with half the original frequency, the wavelength of the wave would increase to 10 meters.

2000 mm is equivalent to 2 m. This can be derived from the fact that 1 m = 1000 mm. Thus, 2000 mm would be equal to 2 m since it is twice the length of 1000 mm. This conversion is important in various fields such as construction, engineering, and science where precision is necessary.

It is crucial to be able to convert between different units of measurement in order to make accurate calculations and measurements.The millimeter is a unit of length that is often used to measure small distances such as the thickness of a sheet of paper or the size of a small component. It is part of the metric system, which is a system of units used across the world that is based on multiples of 10.

This system makes it easy to convert between different units since it is based on a consistent set of rules.For example, to convert 2000 mm to meters, we can simply divide by 1000 since there are 1000 millimeters in a meter. This gives us 2 meters, which is the equivalent length in meters of 2000 millimeters.

Answer:

Third Law Of Motion.

Explanation:

The law of interaction, the third one, explains that if one body exerts a force on a second body, the second body exerts a force equal in magnitude and opposite in direction on the first body.

A newton-meter per second is a unit of both power and energy (option d).

The unit of a newton-meter per second represents the rate at which work is done or energy is transferred. Work and energy are related concepts, and power is the measure of how quickly work is done or energy is transferred.

In physics, work is defined as the transfer of energy that occurs when a force acts on an object and displaces it. The unit of work and energy is the joule (J), which is equal to a newton-meter (N·m). This means that one newton-meter is equivalent to one joule.

Power, on the other hand, is the rate at which work is done or energy is transferred. It is defined as the amount of work done or energy transferred per unit time. The unit of power is the watt (W), which is equal to one joule per second (J/s). Therefore, a newton-meter per second is equivalent to a watt, making it a unit of power.

In conclusion, a newton-meter per second is a unit of both power and energy, as it represents the transfer of energy or work done per unit time.

The magnitude of the average induced emf in the loop during the rotation is 3.7 V.

When a loop of wire is rotated in a magnetic field, an induced electromotive force (emf) is generated in the loop. The magnitude of this induced emf can be calculated using Faraday's law of electromagnetic induction:

ε = -N * (ΔΦ/Δt)

where ε is the induced emf, N is the number of turns in the loop, ΔΦ is the change in magnetic flux through the loop, and Δt is the time interval during which the change occurs.

In this case, the loop has a diameter of 17.5 cm, which corresponds to a radius of 8.75 cm (or 0.0875 m). The area of the loop is given by A = π * r^2, where r is the radius.

Therefore, the initial magnetic flux through the loop is Φ = B * A, where B is the magnetic field strength. Given that the magnetic field is 1.3 T, we can calculate the initial magnetic flux.

Φ = 1.3 T * π * \((0.0875 m)^2\)

Next, we need to calculate the change in magnetic flux as the loop rotates. Since the loop is initially oriented perpendicular to the magnetic field, and then it is rotated to become parallel, the change in magnetic flux is simply the difference between the final and initial magnetic fluxes.

ΔΦ = Φ_final - Φ_initial

Since the final magnetic flux is zero (as the loop becomes parallel to the field direction), the change in magnetic flux is -Φ_initial.

Finally, we can substitute the values into the formula for the induced emf to find its magnitude:

ε = -N * (-Φ_initial / Δt)

In this problem, the time interval Δt is given as 0.15 s.

ε = N * (Φ_initial / Δt)

Calculating the values, we obtain:

ε = N * (1.3 T * π * (0.0875 m)^2) / 0.15 s

Simplifying this expression will give us the magnitude of the average induced emf in the loop during the rotation.
