A wave on a string is described by D(x,t) = (1.2 cm)sin[2 pi (x/(3.9 m) + t/(0.4 s) + 1)], where x is in m and t is in s.
What is the wave speed?
m/s.
What is the wave frequency?
Hz.
What is the wave number?
rad/m.
At t = 0.2 s, what is the displacement of the string at x = 0.6 m?
cm.
Two stationary positive point charges, charge 1 of magnitude 3.45 nC and charge 2 of magnitude 1.50 nC, are separated by a distance of 52 cm. An electron is released from rest at the point midway between the two charges, and it moves along the lin..
how long does it take for a person to radiate. Calculate the time of flight.
A 17g rifle bullet travelling 220 m/s buries itself in a 3.90 kg pendulum hanging on a 3m long string, which makes the pendulum swing upward in an arc. Find out the vertical and horizontal components of the pendulum's displacement.
A rifle with a weight of 35 N fires a 5.0-g bullet with a speed of 250 m/s, If a 675-N man holds the rifle firmly against his shoulder, find the recoil speed of the man and rifle
You measure an electric field of 1.26×106 N/C at a distance of 0.149 m. from a point charge. find the magnitude of the charge
In an X-ray tube electrons strike a tungsten target (W or "wolfram") after being accelerated through a potential difference V0. Estimate the minimum value of V0 required to observe the Kalpha peak.
Charge q is fired through a small hole in the positive plate of a capacitor. If q is a positive charge, does it speed up or slow down inside the capacitor? reply this question using the concept of force.
peg is located a distance h directly below the point of attachment of the cord. If h = 0.90 L, illustrate what will be the speed of the ball when it reaches the top of its circular path about the peg?
A double speed trap is set up on a freeway. One police cruiser is hidden behind a billboard, and another is some distance away under a bridge. As a sedan passes by the first cruiser, its speed is measured to be 99.7 mph.
Protons are projected with an initial velocity v0 = 10360 m/s into a region where a uniform electric field E = 670 N/C is present. The protons are to hit a target that lies a horizontal distance of 1.27 mm from the point where protons are launched..
