How much heat is absorbed by a 27g iron skillet when its temperature rises from 13oc to 23oc?

What can you increase the strength of an electromagnet by

What does the law of conservation of mass state?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
