A 460-Hz tuning fork causes resonance in the tube depicted in the figure below when the length L of the air column above the water is 18.3 and 55.8 cm
Find the speed of sound in air.
What is the end correction to adjust for the fact that the antinode does not occur exactly at the open end of the tube?
What is the net force exerted by these two charges on the third charge = 46.5 placed between and at = -1.235 ? Your answer may be positive or negative, depending on direction of the force.
What are the direction and magnitude of the magnetic force the field exerts on the proton.
Determine decisions from your personal experiences that fit under each of the categories of differential analysis presented in the text, including lease
X-rays having an energy of 300 keV undergo Compton scattering from a target. The scattered rays are detected at 37.0° relative to the incident rays. Find (a) the Compton shift at this angle, (b) the energy of the scattered x-ray, and (c) the energ..
A bat flies toward a wall, emitting a constant sound of frequency 2.00 rm kHz. This bat hears its own sound plus the sound reflected by the wall.
Find out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s2 direction 3° from the direction of velocity towards center of the circle
Two small metallic spheres, each of mass m = 0.212 g, are suspended as pendulums by light strings of length L as shown in the figure below. The spheres are given the same electric charge of 7.9 nC, and they come to equilibrium when each string is ..
A 0.50 kg ball that is tied to the end of a 1.30 m light cord is revolved in a horizontal plane with the cord making a 30° angle, with the vertical. If the cord can withstand a maximum tension of 9.5 N, what is the highest speed at which ball can ..
Compare the kinetic energy of car travelling. Compare the kinetic energy of an 900 kg car travelling at 30 m/s, and a 1,800 kg car at the same speed.
what is the potential difference between the plates. A particular freely falling object requires 1.85 s to travel the last 31.0 m before it hits the ground. From what height above the ground did it fall.
A 400kg piano slides 4.0 m down a 30 degree incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. Find out the force exerted by the man.
A hunter aims directly at the target (on the same level) 115 m away. If the bullet leaves the gun at a speed of 205 m/s, by how much will it miss target.
