Q. A pipe open at one end only has a fundamental frequency of 251 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now, when both pipes vibrate at their fundamental frequencies, a beat frequency of 13 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 343 m/s
Q. A dipole with dipole moment 1.6 {rm nCcdot m} is oriented at 45{^circ} to a 3.4 {rm MN/C} electric field. What is the magnitude of the torque on the dipole?
Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.

assume the roller coaster (h1 = 34 m, h2 = 10 m, h3 = 20) passes point A with a speed of 2.00 m/s. If the average force of friction is equal to one sixth of its weight, with what speed will it reach point B? The distance traveled is 45m.
Two wires are tied to the 500 sphere. The sphere revolves in a horiIzontal circle at a constant speed of 6.8.
The radius of the tires on your car is 0.33m. You drive 1400 m in a straight line. What is the angular displacement of a point on the outer rim of a tire, around the center of tire, during this trip? Suppose the tire rotates in the counter clockwise ..
Tam walks with the velocity of 1.8 m/s west. He does so while riding on a conveyor belt that moves at a velocity of 0.7 m/s west. What is Tam's velocity.
An airplane is flying with a velocity of 95 at an angle of 19 above the horizontal. When the plane is a distance 111 m directly above a dog that is standing on level ground, suitcase drops out of luggage compartment.
The ball is 21.9 m from the goal post. The ball is kicked with an initial velocity of 19.8 m/s at an angle θ above ground. Between what two angles, θ1 and θ2, will the ball clear the 2.74m high crossbar.
