1) A parallel plate capacitor with 4.0 mm plate spacing has circular plates and holds a charge of +/- 6 uC on each plate when it is charged to a potential of 100 V. What is the radius of the plates?
2) You have three 2-uC capacitors. Draw all 3 possible configurations for combining them and calculate the effective capacitance of each configuration.
Two objects of masses 10.0 kg and 5.00 kg are connected by a light string that passes over a frictionless pulley as in figure P4.20. The 5.00 kg object lies on a smooth incline of angle 40 degrees. Find out the acceleration of the 5.00 kg object ..
Some people think that they can stop themselves rushing forward by putting their hands on the dashboard. Find out the mass of the object that has a weight equal to force you just calculated.
A helicopter is ascending perpendicularly with a speed of 5.02 {rm m/s}. At a height of 115 {rm m} above the Earth, a package is dropped from the window.
The ratio of the average acceleration values is a1/a2 = 1.24. Find out the velocity of the car at the end of the initial ten-second interval.
A person walks first at a constant speed of 4.80 m/s along a straight line from point a to point b and then back along the line from b to a at a constant speed of 3.30 m/s. What is her average speed over the entire trip?
For a damped oscillator with a mass of 170g, the spring constant 92 N/m and a damping coefficient of 55g/s, what is the ratio of amplitude of the damped oscillations to the initial amplitude at the end of 22 cycles.
What is the kinetic energy of a ball of mass 16.1 kg at the apex (highest point) of its trajectory, if it is thrown with an initial speed of 45 mph and an initial angle of 42.8 o with respect to the horizontal?
Suppose that the mass of the dishwater is large as much as necessary so that its temperature does not change appreciably.
In one dimension, it is obvious that the force obeying Hook's law is conservative. Consider instead a spring that obeys Hook's law and has one end fixed at origin.
