The moment just after the battery is turned on, what is the voltage across the resistor, the inductor, and the capacitor each? What is the current in the circuit? Explain your reasoning.
An air puck of mass 0.29 kg is tied to a string and allowed to revolve in a circle of radius 1.4 m on a frictionless horizontal table. The other end of the string passes during a hole in the center of the table, and a mass of 0.7kg is tied to it. The..
A 55.1-kg ice skater is moving at 3.99 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. Determine the force exerted by the horizontal rope on her arms
In a photoelectric-effect experiment it is observed that no current flows unless the wavelength is less than 470 nm. What is the stopping voltage required if light of wavelength 410nm is used
Ricardo and Maria both move to the center of the canoe. Ricardo notices that the canoe moves a distance d = 0.37 m relative to a rock that is stationary in the water. What is Maria's mass in kg

A truck weighs four times as much as a car. if the truck coasts into the car at 12km/h and they stick together, what is their fimal velocity.
A dockworker loading crates on a ship findsthat a 18 kg crate, initially at reston a horizontal surface, requires a 78N horizontal force to set it in motion. However, after the crate isin motion, a horizontal force of 56 Nis required to keep it m..
Oppositely charged parallel plates are separated by 6.16 mm. A potential difference of 600 V exists between the plates. What is the magnitude of the electric field between the plates
Vinny (m= 40 kg) is at rest on ice ( which we'll assume is frictionless) holding a gun ( m=1 kg). Each bullet in the gun has a mass of 20 grams and fires at 400 m/s. How much chemical energy was stored in the unfired bullets
You push a 20 kg box from an elevation of zero up a hill. You exerta force of 200 N for 6 m and the box speeds up steadily from restto 2 m/s. What angle does the hill make with the horizontal
