The wave function of a standing wave is y(x, t) = 4.44 mm sin [(32.5 rad/m) x] sin [(754rad/s) t]. For the two traveling waves that make up this standing wave, find the
(a) Amplitude;
(b) Wavelength;
(c) Frequency;
(d) Wave speed;
(e) Wave functions.
(f) From the information given, can you determine which harmonic this is? Explain.

A spring is attached to an overhead beam. If you put a mass of 170 gram on it, and it proceeds to stretch a distance of 7 centimeter, Obtain the magnitude of the downward acceleration
What are the space coordinates of the event in inertial frame S' which is moving in the +x direction at a speed of 0.01c relative to S?
The Sun is a low mass star and so will never have the core fusion reactions of massive stars. Yet, the Sun has iron in its atmosphere, as well as gold, silver and other elements much heavier than iron. Why?
A uniform solid disk with a mass of 23.8 kg and a radius of 0.712 m is free to rotate about a frictionless axle. Forces of 92.0 and 124 N are applied to the disk. Taking the clockwise direction to be the negative direction, what is (a) net torque pro..

A diving board of length 3.00 m is supported at a point 1.00 m from the end, and a diver weighing 530 N stands at the free end (Figure 1) .
A plane flies from base camp to Lake A, 340 km away in the direction 20.0° north of east. After dropping off supplies it flies to Lake B, which is 240 km at 30.0° west of north from Lake A. Graphically find the distance and direction from Lake B to..
A projectile is launched horizontally, to the left, at 50.0m/s off of a cliff that is 80.0 meters tall. Ignore air friction and take g = 10.0 m/s/s (instead of 9.8). Where in the projectile’s motion does it have its minimum speed?
A 79kg person holds out his arms so that his hands are 1.6m apart. Normally, a person's hand makes up about 1% of his or her body weight. For round numbers, we shall assume that all the weight of each hand is due to the calcium in the bones.
