An electron is constrained to the central axis of a ring of charge 1 coulomb and of radius 1 meter. The electrostatic force exerted on the electron can cause the electron to oscillate through the center of the ring. Find the frequency of oscillation of the electron in Hertz.
If vector "B" is added to vector C =3.0i + 4.0J, the result is a vector in the positive direction of the y axis, with a magnitude equal to that of vector "C". What is the magnitude of vector "B".
A 30-06 bullet has a mass of 0.010 kg. If the average force on the bullet is 7200 N, what is the bullet's average acceleration?
Suppose the pressure of the gas equals to p=aV^2, where a is constant. Find the heat transfer to the gas during this process if this is a reversible change.
At one point in a pipeline, the water's speed is 3 m/s and the gauge pressure is 4.00×10^4 Pa. Find the gauge pressure at a second point in the line 11 m lower than the first if the pipe diameter at the second point is twice that at the first.
