A brass cylindrical bar at 300 K has a diameter of exactly 20 mm. An aluminum ring has an inner diameter which is exactly 15 too small to fit over the brass cylinder. To what temperature do you need to heat both the brass cylinder and the aluminum
A proton is placed 4.65 mm from an infinitely long line of charge. The proton is observed to experience an acceleration of 3.34 x 107 m/s2, toward the line of charge, at the moment it is released. Calculate the linear charge density of the line of c
A passenger of mass 50.0 kg is in a car rounding a level curve of radius 100.0 m at a speed of 20.0 m/s. (a) Assuming that friction is the only horizontal force acting on the passenger, find the frictional force. (b) What would happen if is 0.3 m
The center of mass of the ladder is 2.5 m from its base, and the coefficient of static friction between the ladder and the floor is 0.2. How far up the ladder, measured along the ladder, can a 600N person climb before the ladder begins to slip?
A 13 nC charge is located at the origin. What is the strength of the electric field at the position (x,y) = (5 cm, 0 cm)?
A 9.00 g bullet, moving horizontally with an initial speed v, embeds itself in a 1.20 kg pendulum bob that is initially at rest. The length of the pendulum is L = 0.700 m. After the collision, the pendulum swings to one side and comes to rest when
What is the magnitude of the largest pushing force that can be applied to the refrigerator before it just begins to move? Assume g = 9.81 m/s2.
You pull a simple pendulum of length 0.240m to the side through an angle of 3.50degree and release it. a.) how much time does it take the pendulum bob to reach its highest speed? b.) how much time does it take if the pendulum is released at an ang
