Answer: Reflection is the only process in which the wave does not continue moving forward.
Explanation:
Reflection is a process in which the direction of the wave changes when it is exposed to a bounce off barrier. Refraction can be defined as the change in the direction of the wave when the wave passes through one medium to another. Diffraction is a process in which the direction of the wave changes when the wave passes through a particular opening near the barrier.
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that flux is defined as
here we have
now we have
Part b)
Also we know that the radius of the planet is given as
now the electric field is given as
here we have
Answer:
option d is correct
Explanation:
So acceleration is the change in velocity over time, so the first option is correct.
so a = b/t, we can rearrange so that at = v, option d is correct. Solvng for t we have t = v/a, not t = a/v, This is incorrect, So t=Δa/v is the incorrect one and it is your answer.
Answer:
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
