What is the magnitude of the centripetal acceleration of an object on earth's equator owing to the rotation of earth? (b) what would the period of rotation of earth have to be for objects on the equator to have a centripetal acceleration with a magnitude of 9.80 m/s2?

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?
