A 10 kg farm wagon is sitting at the top of a hill that makes a 370 angle with the horizontal when the brake suddenly fails. The cart rolls down the hill for 50 m and then hits a haystack. It plows 2.0 m into the stack before coming to rest.

What is a Geographic test

What is the velocity of a beam of electrons that go undeflected when passing through crossed (perpendicular) electric and magnetic fields of magnitude 1.63*104V/m and 2.50*10-3T, respectively? me=9.11*10-31kg, e=1.60*10-19C.

Gravity pulls gases and dust particles in space toward one another, squeezing them into a smaller and smaller space. The temperature at the center rises high enough for fusion of hydrogen to begin.
