You and your friend Joe are filming a music video. Joe has a spring with spring constant 9.8 N/m and a 0.2-kg mass hanging from the end,
resulting in harmonic motion. You want the metronome to match the
period of the bouncing spring. How long would your metronome's
pendulum have to be?
L =
meters

According to the tide table below what time of day will the highest tide occur?

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
