calculate the density of a nucleus and explain it
Assuming that each nucleus is roughly spherical and that its mass is roughly equal toA (in atomic mass unitsu), what is the density? of a nucleus with nucleon numberA?
When a 58-g tennis ball is served, it accelerates from rest to a speed of 44 m/s. The impact with the racket gives the ball a constant acceleration over a distance of 38 cm. What is the magnitude of the net force acting on the ball?
A solenoid 10.0 cm in diameter and 69.9 cm long is made from copper wire of diameter 0.100 cm, with very thin insulation. What power must be delivered to the solenoid
