What height above compressed spring was block dropped : A vertical spring with a spring constant of 470N/m is mounted on the floor. From directly above the spring, which is unstrained, a 0.30 kg block is dropped from rest. It collides with and sticks to the spring, which is compressed by 2.8cm in bring..

Estimate the energy released during this fission : Suppose a nucleus of 93X236 fissions into two fragments whose mass ratio is 0.33:0.67. With the aid of the drawing, estimate the energy (in MeV) released during this fission.

Determine the average energy needed to produce one in air : One kilogram of dry air at STP conditions is exposed to 1.00 R of X-rays. One roentgen is defined by Equation 32.1 in Section 32.1. An equivalent definition can be based on the fact that an exposure of one roentgen deposits 8.30 x 10-3 J of energy..
