Astrong man is compressing a lightweight spring between two weights. one weight has a mass of 2.3 kg , the other a mass of 5.3 kg . he is holding the weights stationary, but then he loses his grip and the weights fly off in opposite directions. the lighter of the two is shot out at a speed of 6.0 m/s .
what is the speed of the heavier weight?

After an atomic bomb has been dropped, the damage continues to get worse. why is this?

Explain in physical terms how a microwave oven works. what would happen when you put a conductor in the microwave oven? explain.

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?
