Answer:
Explanation:
- given S = distance from the first = 3.20cm = 0.032m, t = 1.30×10−8 s
- acceleration = 0.032 X 2 /(1.30×10−8)^2
a = 3.79 x 10^14m/s^2
E = ma /q = 9.11 x 10^-31 x 3.79 x 10^14 / 1.6 x 10^-19
E = magnitude of this electric field. = 2156.3N/C
b) Find the speed of the electron when it strikes the second plate ; V^2 = 2as
= 2 X 3.79 x 10^14 X 0.032
= 4.92 X 10^6m/s
Answer:
a - As long as the time between 2 events is reconcilable with a light signal, the time between the events, in that frame, can be determined.
Rocks within Earth both expand and contract as P waves pass
Explanation:
Rocks within the earth both expands and contracts as P-waves passes through them. P-waves are elastic waves.
- Elastic waves behaves in such a way that they do not cause permanent deformation of rocks.
- They can be said to cause elastic deformation when they travel through rocks.
- They simply temporarily expand and contract the rock within a short period by causing the vibration of particles of the medium.
- After a short while, the rock returns back to its original position as if nothing has happened to it.
- These elastic waves are better called seismic waves.
- P-waves are primary waves that can travel through any medium.

no
Explanation:
it is faster at the equator
Temperature can change the state from solid to liquid causing it to melting, liquid to gas causing vaporization or a solid to a gas causing sublimation. Pressure alone cannot change the state of matter.
