In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 30-cm-thick 400 kg stationary target and emerges with a speed of 930 m/s. The target is free to slide on a smooth horizontal surface. (a) How long is the bullet in the target?
What average force does it exert on the target?
(b) What is the target's speed just after the bullet emerges?

heat the gas and measure the pressure

this could be newton#'s law of cooling. the cooling curve is exponential

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.

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.
