What is the temperature dependence of the jump rate ? where does it come from?~exp(-q/rt); it comes from the fact that at finite temperature the atoms exchange energy via vibrational ""collisions"".

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
