physics
Two particles are in a uniform electric field whose value is +4000 N/C. The mass and charge of particle 1 are m1 = 1.0x10-5 kg and q1 = -15 µC, while the corresponding values for particle 2 are m2 = 3.0 x10-5 kg and q2 = +35.0 µC. Initially the particles are at res...

A Carnot engine operates between 170°C and 20°C. How much ice can the engine melt from its exhaust after it has done 6.0 104 J of work? i need a step by step process. you don't have to give me the answer.

Physics
One gram of water changes from liquid to solid at a constant pressure of 1.00 atm and a constant temperature of 0°C. In the process, the volume changes from 0.60 cm3 to 1.14 cm3. Find the work done on the water? Find the change in the internal energy of the water?

physics
A tennis player standing 11.5 m from the net hits the ball at 2.60° above the horizontal. To clear the net, the ball must rise at least 0.252 m. If the ball just clears the net at the apex of its trajectory, how fast was the ball moving when it left the racquet?
