An electric car accelerates for 9.9 s by drawing energy from its 340-V battery pack. During this time, 1700 C of charge pass through the battery pack. Find the minimum power rating of the car

In one hand you hold a. 12-kg apple, in the other hand a. 20-kg orange. The apple and orange are separated by. 75 m. What is the magnitude of the force of gravity that (a) the orange exerts on the apple? (b) the apple exerts on the orange?

An blank is an object that allows only some electrons to go through it

How do you calculate the total resistance of a series circuit

A force of 825 N is needed to push a car across a parking lot. Two students push a car 35 m. How much total work is done?

Air enters the combustor of a jet engine at P1 = 10 atm, T1 = 1000oR, and M1 = 0.2. Fuel is injected and burned, with a fuel-air ratio (by mass) of 0.06. The heat released during the combustion is 4.5 * * 108 ft-lb/slug of fuel.

How do mountins building and volcanos relate to plate motion at convergent boundaries

A 20kg box is dropped 13m. how much work is done

Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimum necessary. Find the magnitude of the frictional force between the person and the wall

A ball is being rolled by a normal push of 1000N. it is opposed by friction which has a force of 0.3kN and air resistance which has a force of 23N. Calculate the resultant force.
