Solve the all parts of given problem:
Problem: The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W=44300 N. The lift force L generated by the rotating blade makes an angle of 21.0° with respect to the vertical.
Part A: What is the magnitude of the lift force?
Part B: Determine the magnitude of the air resistance R that opposes the motion.
I want help to find the magnitude of the air resistance R that opposes the motion.
Electric breakdown (sparks) occur in air if the electric field reaches 3×106 N/C. At this field strength, free electrons present in the atmosphere are rapidly accelerated to such large speeds that upon impact with atoms they knock electrons off of th..
