Explanation:
Potential energy is stored energy, so it is not in motion. Kinetic energy is the energy in motion.
Answer:
Distance s=ut+1/2 at^2
If it’s released then this becomes
s=1/2at^2
s=1/2 *9.81*9
s=44.1 m
Explanation:
Answer:
a. Fr^2 = 119.7^2 + 49.9^2 = 16,818.1
Fr = 129.7 N.
b. tanA = Y/X = 49.9/119.7 = 0.41688
A = 22.63o = Direction.
Explanation:
When a neutron or a proton in the nucleus changes a gamma ray is produced (gamma rays are electromagnetic waves)
When an electron drops from a higher energy level to a lower energy level an electromagnetic wave is give off.
