A particle moves horizontally in uniform circular motion, over a horizontal xy plane. At one instant, it moves through the point at coordinates (2.50 m, 2.50 m) with a velocity of -5.00 i hat m/s and an acceleration of +11.5 j hat m/s2. What are the coordinates of the center of the circular path?
(x, y) =
Sketch a graph of maximum kinetic energy, KE max against visible light frequency, v for this experiment Label threshold frequency Vc.
A 2.30-?F capacitor is fully charged by being connected to a 6.0-V battery, Calculate the maximum current in the inductor, Calculate the frequency of oscillation of the LC circuit
Two students are on a balcony a distance h above the street. One student throws a ball vertically downward at a speed vi; at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in t..
What minimum constant acceleration the aircraft requires.
explain the energy released in the explosion. A rock stuck in the tread of a 59.0 cm diameter bicycle wheel has a tangential speed of 3.20 m/s. When the brakes are applied, the rock's tangential deceleration is 1.20 m/s^2
Let us take half the terminal speed as a reasonable "upper bound" beyond which we should not use our constant acceleration free-fall relationships.
Three equal point charges, each with charge 1.50, are placed at the vertices of an equilateral triangle whose sides are of length 0.550. What is the electric potential energy of the system? (Take as zero the potential energy of the three charges w..
It collides with and sticks to the spring, which is compressed by 2.50 cm in bringing the block to a momentary halt. Assuming air resistance is negligible; from what height (in cm) above compressed spring was the block dropped.
The Moon moves noticeably on the celestial sphere over the space of a single night. To show this, calculate how long it takes the Moon to move through an angle equal to its own angular diameter (0.5 degrees) against the background of the stars. Gi..
Two speakers, one directly behind the other, are each generating a 152-Hz sound wave. What is the least separation distance between the speakers that will produce destructive interference at a listener standing in front of them.
