An airplane flies east at a speed of 120 m/s the airplane has a mass of 3200

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

An object has a weight of 500 on earth what is the mass of this object

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
