Q.If the accelerating plates are 1.05 cm apart, and have a potential difference of 2.20×104 V, find the change in electric potential energy for an electron that moves from one accelerating plate to the other.
Q. A small object is attached to the end of a string to form a simple pendulum. The period of its harmonic motion is measured for small angular displacements and three lengths, each time clocking the motion with a stopwatch for 50 oscillations. For lengths of 1.000 m, 0.750 m, and 0.500 m, total time.
Find out the friction force on the box
A weather vane at first at rest has a moment of inertia of 0.111 kg • m2 about its axis of rotation. A 53.0 g piece of clay is thrown at the vane and sticks to it at a point 19.5 cm from the axis. The initial velocity of the clay is 20.0 m/s, directe..
What is linear acceleration
What is the maximum speed with which a 1350kg car can round a turn of radius 71m on a flat road if coefficient of static friction between tires and road is 0.40.
A worker stands still on a roof sloped at an angle of 21° above the horizontal. He is prevented from slipping by a static frictional force of 400 N. Find out the mass of the worker.
A string of mass 0.0003kg/m and 0.5m long is vibrating 200 cycles per second. What must be the tension? What hanging mass would generate this tension? I got 12N for tension. Is this correct? And how would you solve for hanging mass.
A car is traveling north at 17.7m/s. After 12s its velocity is 14.10m/s in the same direction. Find the magnitude and direction of the car's average acceleration.
Most dentist in the United States are make as the majority of nurses are female. These differences show how different cultures define.
Using Einsteins formula
If a 200 N force F1 is applied to the piston with the 4 cm diameter, Calculate the magnitude of the force F2 that can be resisted by the piston with the 10 cm diameter? Ignore the weights of the pistons.
A helicopter flies at a constant altitude towing a mass M of 119 kg. The helicopter and the mass have a horizontal acceleration of 2.54 m/s^2. Ignore air resistance find the tension in the cable.
A spider of mass m is sitting in a perfectly symmetric web (in a vertical plane with 45 angles between the web lines), where Ti's denote the tensions along the lines that are connected to the spider at the center with i = 1, 2, 3, 4, 5, 6, 7, 8. The ..
