Technician A says a special puller and installer tool is required to remove and install the vibration damper. Technician B says if the inertia ring on the vibration damper is loose, the damper must be replaced. Who is right?

If you fall and skid to a stop on a carpeted floor, you can get a rug burn. Much of this discomfort comes from abrasion, but there can also be a real burn where the skin was too hot. How does this happen?

What happens to the inertia of an object of its mass is decreased?

An object has an acceleration of 24 m/s/s. How long would it take the stationary object to reach a velocity of 6.8 m/s?

What is normal distribution in statistics?

A linearly-polarized electromagnetic (EM) wave has an electric field with amplitude 1000 V/m. You hold a a linear polarizer in front of it and rotate the polarizer so that all of the EM wave is blocked. You then rotate the polarizer 30 degree.
