An egg, which can be assumed to b a 5-cm diameter sphere having the thermal properties of water, is initially at a temperature of 4degC. It is immersed in boiling water at 100degC for 15min. The convection coefficient from the water to the egg can be assumed to be 1700 W/m2-K. What is the temperature of the egg center at the end of the cooking period

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
