An ice cube tray makes a dozen 20.0 g ice cubes. If the ice cube tray is filled
with 0.00°C water, and then frozen into
ice cubes, find Q, the change in heat
energy of the water.

How would doubling the made of an object change the objects potential energy

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

What causes the development of most clouds and precipitation in the atmosphere?
