Answer:
Torque, 
Explanation:
Given that,
Coordinates, 
Force acting on the flea, 
Let 
is the net torque about the origin on a flea. It is given by the following formula :
So, the net torque about the origin on a flea is 
. Hence, this is the required solution.
E = 1/2 m v^2
108000m /3600 = 30m/s
E = 1525 * 0.5 * 30 = 22875 J
Answer:
Answer:
f) The puck conserves its original momentum but loses some, but not all, of its mechanical energy.
Explanation:
It is a case of perfectly inelastic collision . So momentum will be conserved because no external force acts on them during the collision . But there will be loss of energy ( kinetic energy ) . It will be in the form of sound or heat that is produced during collision. They will still have some kinetic energy even after the collision.
Explanation:
I think that the answer is B that the sun (DOES NOT) support the processes of plate tectonics
