Apilot is flying a small airplane at 40.0 m/s in a circular path with a radius of 200.0 m. the pilot has a mass of 80.5 kg. find the magnitude of the centripetal forces that maintains the circular motion of the pilot. 16.1 n 644 n 659 n

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

If forces acting on an object are unbalanced. true or false

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
