A wheel has a radius of 0.5 m. If the wheel rotates on its axis through an angel of 46 degrees, what distance does a point on the rim of the wheel move?
A man pushes a lawnmower for 13.1 m along a handle that makes a 28.2° angle with the ground. He pushes with a force of 42.8 N even as the force of friction between the lawnmower and the ground is 13.7 N.
Positive point charges q and 2q are located at x = 0 and x = 3d, respectively. What is the electric field at x = d (point P)? (Use any variable or symbol stated above along with the following as necessary: k for Coulomb constant.) magnitude E = di..
