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.
Find out the magnitude of the impulse delivered to a soccer ball when a player kicks it with a force of 1350 . Assume that the player's foot is in contact with the ball for 6.00×10-3.
An electron and a proton, starting from rest, are accelerated through an electric potential difference of the same magnitude. In the process, Find the ratio ve/vp
The ball curves because it is spinning at an average angular velocity of 370 rev/min (assumed constant) on its way to the catcher's mitt. Illustrate what is the angular displacement of the baseball (in radians) as it travels from the pitcher to t..
At rest, the car's horn sounds at a frequency of 455 Hz. The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-third the car's speed hears a frequency of 427 Hz. What is speed of the car.
A certain atom of has 89 protons. Assume that the nucleus is a sphere with radius 7.25 fm and with the charge of the protons uniformly spread through the sphere. At the nucleus surface what is the magnitude of the electric field produced by the pr..
A 55.0 kg circus performer oscillates up and down at the end of a long elastic rope at a rate of once every 8s. The elastic rope obeys Hooke's Law. By how much is rope extended beyond its unloaded length while the performer hangs at rest?
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..
A vertically hanging steel wire has the following properties. Length=8.75m, Cross-Sectional area= 0.375 cm cubed. Y=2.10x10^11 Pa, B=1.62x10^11 Pa, S= 0.871x10^11 Pa, Proportional Limit=3.27x10^8 Pa, breaking stress=17.4x10^8 Pa.
How high above the ground will the ball be when it gets to Julie? (note, the ball may go over Julie's head.) 7) Below is some space to write notes on this problem.
Shantel was the sole owner of the residence until it was sold. Explain how much of the gain may Shantel and Daron exclude?
Two balls, of masses = 49 and = 67 , are suspended as shown in the figure. The lighter ball is pulled away to a 66 angle with the vertical and released. suppose that positive axis is directed to the right. What is the velocity of the lighter ball ..
When the starter motor on a car is engaged, there is a 330A current in the wires between the battery and the motor, What minimum diameter can the wires have if the voltage drop along the wires is to be less than 0.45V
