Dw) 3. Kimberly is using a rope to lift a 1.5 kg box up at an acceleration of 2 m/s2 What is the upwards force of the rope on the box?

Which is not one of the major climate zones? question 3 options: rain forest polar tropical temperate

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

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.
