<span>Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive mistakes were selected when they were formed.</span>
A centripetal force does that.
Answer:
a) h = 0.0088 m
b) Kb = 794.2J
c) Kt = 0.88J
Explanation:
By conservation of the linear momentum:
By conservation of energy from the instant after the bullet is embedded until their maximum height:
h=0.0088m
The kinetic energy of the bullet is:
The kinetic energy of the pendulum+bullet:
