C) Light in vacuum
Light in a vacuum, on the order of magnitudes, travels much faster than the other three. In fact, the speed of light in a vacuum is the theoretical limit of how fast anything can travel.
Answer:
(The first law of thermodynamics) When you put a hot object in contact with a cold one, heat will flow from the warmer to the cooler. As a result, the warmer one will usually cool down and the cooler one will usually warm up. Eventually, they will reach the same temperature and heat flow will stop.
Answer:
73 degree
Explanation:
Angle of incidence = 17 degree
According to the laws of reflection, the angle of incidence is equal to the angle of reflection.
So, angle of reflection = 17 degree
Angle from the surface = 90 - 17 = 73 degree
