0.50kg ball is traveling to the right with a velocity of +10.0m/s. The ball collides elastically with a second ball, which has a mass of 1.5kg and is also traveling to the right with a speed of 4.0m/s. Calculate the final velocities of both balls, assuming a head - on collision.​

True or false graphs must include scales that increase by the same amount

What is a subatomic particle with a negative charge and very little mass?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
