Sa result of his observations, ole roemer concluded that eclipses of io by jupiter were delayed by 22 min during a six–month period as the earth moved from the point in its orbit where it is closest to jupiter to the diametrically opposite point where it is farthest from jupiter. using the value 1.50 108 km as the average radius of the earth's orbit around the sun, calculate the speed of light from these data.

50 g of ice at 0°c is dropped in a beaker containing 100 g of water at 0°c. what will be the contents of the beaker after 5 hours? assume that the room temperature is 0°c.

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

Which composition of water moves to begin a deepwater current?
