It will be approximately equal.
<h3>How will the final kinetic energy change?</h3>
We can infer that all of the energy in the electron is Potential energy (PE) because the energy provided by the photon is hardly enough to outweigh the work function.
It will gain kinetic energy (KE) as it advances in the direction of the anode because it is moving through an electric field. All of the PE will have been transformed to KE by the time it reaches the anode.
According to the question
K = hf - W
W = Work function
The energy of photons is comparable. After conversion, there was only a little amount of KE remaining.
Therefore, PE (W) essentially equals KE (K).
It will about be equal.

We'll look at two properties:
1. The variation in temperature
2. The material's heat transfer coefficient
By taking an example;
Use a circular rod made of a certain material (for example, steel) that is insulated all the way around.
One end of the rod is immersed in a huge reservoir of 100°C water, while the other is immersed in water at 40°C. The cold water is kept in an insulated cylinder on both sides. The temp of the chilly water is measured using a meter as a time - dependent.
Conclusion of experiment;
- Heat is transferred from a hot location to a cooler region.
- Whenever heat is applied to a body, its thermal power rises, and its temperature rises.

Answer:
65
Explanation:
as i = r , so i + i = 130
so , i = 130/2 =65
Answer:
W = Fd = 400(20) = 8000 J
Explanation:
Answer:
(a): The frequency received by the observers is f'= 138,062.28 Hz.
(b): When the plane flies directly away from them, they receive a frequency of f'= 1772.46 Hz.
Explanation:
Vf= 333.33 m/s
Vo= 0 m/s
V= 342 m/s
f= 3500 Hz
(a) f' = f * ( V / (V - Vf) )
f'= 138062.28 Hz
(b) f'= f* ( V / (V - (- Vf) )
f'= 1772.46 Hz
