A 3. 00-kg rifle fires a 0. 00500-kg bullet at a speed of 300 m/s. Which force is greater in magnitude: the force that the rifle exerts on the bullet or the force that the bullet exerts on the rifle?.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the answer would be c. motion and direction

i hope this : )

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it

false

hope this : d
