A very long cylindrical shell with a radius of 50 mm carries a uniform surface charge density of 1.0×10^−9C/m^2. What is the electric field strength at a distance of 3.3 mm from the surface of the shell.

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

An object's buoyant force and weight mean the same thing.a. trueb. false

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
