One hazard of space travel is debris left by previous missions. There are several thousand objects orbiting Earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint. Calculate the force exerted in newtons by a 0.100 mg chip of paint that strikes a spacecraft window at a relative speed of 3.00 β 103 m/s and sticks, given the collision lasts 6.00 β 10β8 s. (Enter the magnitude.)

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

An insulated thermos contains 148 g of water at 72.7 Λc. you put in a 11.7 g ice cube at 0.00 Λc to form a system of ice + original water. the specific heat of liquid water is 4190 j/kgβ’k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
