Hope I helped. :)
Answer:
Explanation:
Ultraviolet radiation has shorter waves than blue or violet light, and thus oscillates more rapidly and carries more energy per photon than visible light does. Does ultraviolet rays carry more energy? The distinguishing factor among the different types of electromagnetic radiation is their energy content.
Options A and C are correct but if you compare their masses, person has negligible mass compared to car. So a car at the top of the hill has the most potential energy.
Answer:
2.15 m
Explanation:
u = 2.2 m/s, v = 0, uk = 0.115
a = uk x g = 0.115 x 9.8 = 1.127 m/s^2
Let s be the distance traveled before stopping.
v^2 = u^2 - 2 a s
0 = 2.2^2 - 2 x 1.127 x s
s = 2.15 m
