The downward acceleration of a falling body on earth is 9.81m/s2. on the moon the same quantity is 1.62m/s2. an astronaut in a space suit has a mass of 145kg. (a) what is the astronaut’s weight on earth? (b) on the moon? (c) what is the astronaut’s mass on the moon?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud
