The golfer in the photo is taking a swing. The golf club starts at point a and ends at point e. The kinetic energy of the club at point c is more than potential energy of the club at point B. Does this mean that the law of conservation of energy is violated? Why or why not?

In what direction does the medium move relative to the direction of the wave? explain.

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
