The amount of charge that passes through a filament of a certain lightbulb in 1.76 s is 1.63 C.
(a) Find the current in the bulb.
(b) Find the number of electrons that pass through the filament in 4.53 s.
(c) If the current is supplied by a 12.0-V battery, what total energy is delivered to the lightbulb filament?
(d) What is the average power?

Calculate the magnitude of the planes acceleration. On a level road with its brakes on, a car traveling at 93 km/hr stops within 87 m when the brakes lock and the car slides.
A 1030 Kg car going 3.4m/s through a parking lot hits and sticks to the bumper of a stationary 1140 kg car. Find the speed of the joined cars immediately after the collision
If the ball is free from rest at a height of 0.67 above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? Suppose the ball is a solid sphere of radius 2.2 and mass 0.14.
Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 2.5 cm in diameter and carries a current of 55 A. If the bird's feet are 3.9 cm apart, calculate the potential difference between its feet. (Th..
