A4.79 g bullet moving at 642.3 m/s penetrates a tree trunk to a depth of 4.35 cm. use work and energy considerations to find the magnitude of the force that stops the bullet. answer in units of n.

Asteady current of 1 ais flowing through a conducter calculate the number of electrons that flows through conductor in 1second

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?
