13) A 4.00 kg box is pushed 2.00 m across a level surface by an applied force of 32.0 N, 0°. The box then slides an additional 3.00 m before coming to a rest. (a) Determine the amount of friction. (b) Determine the box’s maximum speed over the 5.00 m distance traveled

so easy. just google the electromagnetic waves and it’ll pop up.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
