Rhea is running towards Sean and kicks a soccer ball to
him. Sean is standing still.
Which statement best describes the speed of the ball
from Sean's frame of reference and Rhea's frame of
reference?
O The speed of the ball from Sean's reference frame
would be greater than the speed of the ball from
Rhea's reference frame.
O The speed of the ball from Sean's reference frame
would be less than the speed of the ball from Rhea's
reference frame.
The speed of the ball from Sean's and Rhea's
reference frames would be 0 km/h.
O The speed of the ball from Sean's and Rhea's
reference frames would be less than 0 km/h.

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.
