A 3.0A current is at right angles to a 0.55T magnetic field. The wire carrying the current is 1.0m long. How strong is the force that acts on the wire?
Two speakers, one directly behind the other, are each generating a 439-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? Take the speed
A 310 kg wooden raft floats on a lake. When a 75 kg man stands on the raft, it sinks 3.2 cm deeper into the water. When he steps off, the raft vibrates for a while. What is the frequency of the vibration?
A stone is thrown at an angle of 30.0 above the horizontal from the top edge of a cliff with an initial velocity of 17 m/s. A stopwatch measures the stone's trajectory time from the top of the cliff to the bottom at 6.50 s. What is the height of t
