Asmall planet travels about a star with an orbital semimajor axis equal to 1 in the units chosen. calculate the ocations of the 2: 1, 3: 2, 99: 98, 100: 99 ressonaces of the test particles with the planet.

can someone show me how to do this ! ?

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

Which object is most likely represented by a dot?

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.
