A proton moves at constant velocity in the +y direction, through a region in which there is an electric field and a magnetic field. The electric field is in the +x direction, and has magnitude 300 V/m. The magnetic field is in the -z direction, and has magnitude 0.45 T. What is the magnitude of the net force on the proton?Fnet = NWhat is the speed of the proton?v = m/s

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•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?
