Answer with Explanation:
We are given that
Electric field vector=
Magnetic field vector=
We have to find the direction of propagation of the wave.
We know that
The direction of propagation of wave=
The direction of propagation of wave=
Because ()
The wave propagate in -z direction.
Therefore, the component of the vector is (0,0,-1).
Hence, the direction of the propagation of wave is - z direction and component of direction of propagation vector is (0,0,-1).
Answer:
Explanation:
Speed experimented by the ball before and after collision are determined by using Principle of Energy Conservation:
Before collision:
After collision:
The magnitude of the impulse delivered to the ball by the floor is calculated by the Impulse Theorem:
