1. When a mass of 0.5 kg is attached to a certain spring, the spring stretches a
distance of 0.1 meters,
a. What is the k-constant of this spring?

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?

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

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.
