What happens to a wave when it reflects against a fixed boundary? Comment on the direction of motion, and the orientation of the reflected wave (Is it upright or inverted after reflection)
What happens to a wave when it reflects against a free or loose boundary? Comment on the direction of motion, and the orientation of the reflected wave (Is it upright or inverted after reflection)
How does tension affect the speed of a wave? (As the tension in a string increases/decreases, the speed of a wave increases/decreases)
What is the effect of damping on the amplitude of a wave?
How does changing the frequency affect the speed of a wave?
When two pulses with a positive displacement meet at the same point, the resulting displacement of the string is (greater than/less than/the same as) the displacement of the original pulses.
When a positive and a negative pulse meet at a point, the resulting displacement is (greater than/less than/the same as) the displacement of one of the original pulses.

Find the external work done on the block
: A block of mass 2 kg moves on a frictionless incline (none of the forces on the block are shown). Its initial velocity is v_0 = 4 m/s, and it slides a vertical distance h = 20 m up the slope and its final velocity is v_f = 3 m/s. Find the external..

Duct with a mass flow rate
: Air at 35°C and 1 bar enters a duct with a mass flow rate of 1 kg/s. Saturated liquidwater at 20°C is sprayed with a mass flow rate of 10 g/s and enters the duct parallel to the air. At the duct exit all the liquid water has evaporated so that it ..
