A piano wire with mass 2.85 g and length 82.0 cm is stretched with a tension of 35.0 N. A wave with frequency 120 Hz and amplitude 1.40 mm travels along the wire. Calculate the average power carried by the wave. What happens to the average power if t..
A 200g ball is tied to a 1.0 meter long string and released from rest @ 60 degree angle. it swings down and at the very bottom collides with a 1.0kg block. the block is resting on a frictionless surface and is connected to a 20cm long spring with ..

A driver travels northbound on a highway at a speed of 22.0 m/s. What frequency does the driver detect after the police car passes him
Two automobiles are equipped with the same single-frequency horn.When one is at rest and the other is moving toward an observer at15.6 m/s, a beat frequency of 5.52 Hz is heard. What is thefrequency the horns emit? Assume T = 20°C .
Carbon disulfide (CS2) has a vapor pressure of 300 Torr at room temperature, estimate the average time between collisions that the gas is experiencing inside the test chamber
As two trains move along a track, their conductors suddenlynotice that they are headed toward each other. The figure givestheir velocities v as a function oftime t as the conductors slow the trains.
a .30kg puck initially at rest on a frictionless surface is struck by a .2kg puck that is initially moving along the
I've been looking around about LCD monitors, and how they polarise light. When a pixel needs to be black, the light is "twisted" so that it can't go through the polarising sheet in front. What happens to this light? Does it relfect back into the s..
The coefficient of static friction between the m =2.90 kg crate and the 35.0°incline of the figure below is 0.320.What minimum force vector F must be applied to the crate perpendicular tothe incline to prevent the crate from sliding down the incline?
