Technician A says that all friction and steel plates in a clutch pack should be replaced during and overhaul. Technician B says that the automatic transmission fluid cooler should always be flushed when a unit is rebuilt or replaced.

Cold water (cp = 4180 J/kg·K) leading to a shower enters a thinwalled double-pipe counterflow heat exchanger at 15°C at a rate of 1.25 kg/s and is heated to 60°C by hot water (cp = 4190 J/kg·K) that enters at 100°C at a rate of 4 kg/s.

Determine the magnitude of the acceleration for the speeding up phase.

The experimenter fom the video rotates on his stool, this time holding his empty hands in his lap. You stand on a desk above him and drop a long, heavy been bag straight down so that it lands across his lap, in his hands. what happens?
