Answer:
Rectilinear propagation describes the tendency of electromagnetic waves to travel in a straight line. Light does not deviate when travelling through a homogeneous medium, which has the same refractive index throughout; otherwise, light suffers refraction.
Answer:
Potential energy is stored energy and the energy of position––gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges. Everything is made of tiny particles called atoms.
Answer:
A. Here object is moving with increasing velocity
B. Here the object is moving with decreasing velocity that is it is decelerating
C. Here the initial and final velocity are the same so the object moves at constant velocity
D. Here the object started from rest but reached a certain velocity with time so a non zero acceleration was attained
-10/3m/s2. The formula for acceleration is (Final speed - initial speed)/ time.
Thus, (0m/s - 10m/s)/3s is 10m/s/3s which then can be simplified to /10/3m/s2
