When tires are installed or reinstalled on a car, they are usually first balanced on a device that spins them to see if they wobble. A tire with a radius of 0.380 m is rotated on a tire balancing device at exactly 460 revolutions per minute. A sma
Three polarizing filters are stacked, with the polarizing axis of the second and third filters at angles of 19.0^circ and 68.2^circ, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 7
What is the diameter of the disk of the Milky Way?

If the car starts at height h= 3.00 R and the radius is R_1 = 24.0 m, compute the radial acceleration of the passengers when the car is at point C, which is at the end of a horizontal diameter.
A cart loaded with bricks has a total mass of 21.2 kg and is pulled at constant speed by a rope. The rope is inclined at 27.2 ? above the horizontal and the cart moves 27.1 m on a horizontal floor. The coefficient of kinetic friction between groun
A 50-kg student on a sled starts from rest at a vertical height of 20 m above the horizontal base of a hill and slides down.
If you wanted to move an electron from the positive to the negative terminal of a 12V the battery, how much work would you need to do on the electron?
A car is driven 145 km west and then 50 km southwest. What is the displacement of the car from the point of origin (magnitude and direction)?
