Infra-red radiation has a slightly longer wavelength than red light ...
the longest wavelength that is visible to the human eye.
Although infrared can't be detected by the eye, we do have other
receptors that CAN detect it. They are some of the nerve endings
in our skin. When infrared radiation hits these, it produces the feeling
of warmth. Infrared radiation carries heat energy.
Answer:
Δ KE = -495 J
Explanation:
given,
mass of the ice hockey player = 110 Kg
initial speed = 3 m/s
final speed = 0 m/s
distance, d = 0.3 m
change in kinetic energy


Δ KE = -495 J
Hence, the change in kinetic energy is equal to Δ KE = -495 J
Answer:
0.5A as in a series circuit the current is the same everywhere
