Afishermen reels in 5m of line while landing a fish using a constant forward pull of 65n. if the line is at an angle or 35 degrees to the horizon (direction fish is being pulled) how much work does the tension in the line do on the fish?

How is the gravitational force related to the distance between two objects?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
