Consider the following special cases of collisions. in all cases, a cart of m 1 comes in with a velocity v and hits a cart m 2 at rest. most of these are answerable with either intuition or with mathematics. compute v 1 v and v 2 v 2 when: the collision is elastic, and both carts are the same mass? the collision is inelastic, and both carts are the same mass?

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.

Aseries circuit contains a 30 e resistor, a 20 resistor, and a 10 resistor. the power supply provides 100 v to the circuit the current in the 10 resistor, to two significant figures, is a.
