A roller coaster loop has a frequency of .88 Hz. The loop has a radius of 11.932 m. The coaster has a mass of 543 kg. Find the velocity of the loop and then find the Fn of the roller coaster at the top of the loop. All work needs to be shown

Astone weighing 1.5 kilograms is resting on a rock at a height of 20 meters above the ground. the stone rolls down 10 meters and comes to rest on a patch of moss. the gravitational potential energy of the stone on the moss is joules.

The energy produced as a result of this flow of electrons from atom to atom is called
