How would you calculate many electrons are transferred with each rotation by the Van de Graff generator? As is known, the Van De Graff generator is spherical and the one I used in particular had a circular summit that stuck out from the very top. I put a material on top of it, and it only took one rotation--or crank--to knock the material off from the machine and onto the ground.
At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball's acceleration is 810 m/s2, find the magnitude of the net force acting on the soccer ball

The primary coil of a transformer has 232 turns; the secondary coil has 1900 turns. An alternating current is sent through the primary coil. What is the emf amplitude in the secondary
Two identical spacecraft are to be accelerated by rockets. The first rocket fires with a force 4 times as large as that of the second rocket. The acceleration of the first rocket is how many times as vast as the acceleration of the second rocket.
if the resistance in a series RLC circuit remains the same but the capacitance and inductance are doubled, how will the resonant frequencey of the circuit change
What is acceleration due to gravity
Suppose that the voltage of the battery in the circuit is 3.3 V, the magnitude of the magnetic field (directed perpendicularly into the plane of the screen) is 0.66 T, and the length of the rod between the rails is 0.23 m. Assuming that the rails are..
Two thin beams are joined end-to-end to make a single object. The left beam is 11.9 kg and 1.00 m long and the right one is 41.1 kg and 2.00 m long. What is the gravitational torque on the objects about an axis through its left end
What is the magnitude of the torque about the point where the beam is bolted into place.
