Afirst-order low-pass instrument must measure hummingbird wing displacements (assume sinusoidal) with frequency content up to 100hz with an amplitude inaccuracy of less than 5%. what is the maximal allowable time constant for the instrument? what is the phase angle at 50 hz and at 100hz

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
