two tuning forks oscillating coherently and in phase at 1200Hz are separated by 0.35m.
a) Calculate the angles of maximum intensity on a circular wall 10m radius and centered on the forks.(angles should extend over the full range 0-360 degrees.)
b) Calculate the angles of minimum intensity.
c) What is the phase angle difference between the waves at 40 degrees lab angle?
Determine out the angle with respect to the horizontal (angle of deviation) of the beam as it emerges from the prism.
A ball is thrown upward from a platform 4.6 m high with a speed of 16 m/s, What is the magnitude of its velocity when it hits the ground
how far from the woman will he be now. How various revolutions will the car have gone through when the magnitude of its total acceleration is 3.30 m/s^2.
A nonconducting solid sphere of radius R has a volume charge density that is proportional to the distance from the center. That is, ? = Ar for r R, where A is a constant. (Use the following as necessary: 0, A, r, and R, as necessary.)
Two identical small insulating balls are suspended by separate 0.22-m threads that are attached to a common point on the ceiling. Each ball has a mass of 8.10 10-4 kg.

Superman meets an asteroid in outer space and hurls it at 90m/s. The asteroid is five hundred times more massive than Superman is. In the strip, Superman is seen at rest after throw. Taking physics into account, what would be his recoil speed.
A bucket filled with dirt of mass 22 kg is suspended by a rope that hangs over a pulley of mass 31kg and radius 0.15 m. everything is at first at rest.
The brakes are applied and the bicycle is brought to a uniform speed. During braking , the bicycle covers a translational distance of 10m, Evaluate how many turns that each wheel would make during braking.
The first active volcano observed outside the Earth was discovered in 1979 on Io, one of the moons of Jupiter. Assume a volcano on another moon is observed to be ejecting material to a height of about 2.19 x10^5 m.
A car drives straight off the edge of a cliff that is 47.00m high. The police at the scene of the accident observed that the point of impact is 122 m from the base of the cliff. How fast was the car travelling when it went over the cliff.
