An 85-kg man plans to tow a 109 000-kg airplane along a runway by pulling horizontally on a cable attached to it. suppose that he instead attempts the feat by pulling the cable at an angle of 9.08 above the horizontal. the coefficient of static friction between his shoes and the runway is 0.77. what is the greatest acceleration the man can give the airplane?

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?

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.
