If a 28 Newton force is used to compress a spring with a spring constant of 4.0 × 102 N/m, find what is the resulting spring compression?
Light of intensity I0 and polarized horizontally passes through three polarizes. The first and third polarizing axes are horizontal, but the second one is oriented 20.0° to the horizontal. In terms of I0, what is the intensity of the light that pa..
A photoflash unit makes a very bright light for a very short time. Discuss differences in the exposure of the film with and without a flash unit. Consider the f-stop and shutter speed in your deliberation.
a wooden plank of length l and mass m is supported by an axle that passes through its center. a small package of mass
A firecracker resting on a level street explodes into three pieces of equal mass. Immediately after the explosion, the first piece is moving north at 125 m/s, and the second piece is moving east at 75.0 m/sec. What is the velocity of the third piece ..
Consider an organ pipe 2.1 m long that is closed at one end and open at the other. What is the fundamental frequency of the pipe
Consider a circuit containing a resistor withR = 2600 Ω and acapacitor with C = 4.9µF. At what frequency does the reactance of the capacitorequal the resistance of the resistor?
Racing drivers like to warm up the tyres of their car as soon as possible. One reason is that warm tyres grip the road better but the temperature also affects the pressure of the air into he tyres.
A potter's wheel (a solid, uniform disk) of mass 5.7 kg and radius 0.65 m spins about its central axis. A 2.1 kg lump of clay is dropped onto the wheel at a distance 0.41 m from the axis. Calculate the rotational inertia of the system.
