Toss™ MachineGreat machine I use it for front, side and back toss. It gives a strike all the time but with variation that lets you work in and out without having to move it. The balls sometimes don#039;t roll down sometimes but it is just a nice break. Can#039;t say enough nice things about this thing. 4 Toss Machine

ProblemA 2g pingpong ball rubbed against a wool jacket acquires a net positive charge of 1 µC . Estimate the fraction of the ball's electrons that have been removed. Solution If half the ball's mass is protons, their number (equal to the original number of electrons) is 1 g=m p. The number of electrons removed is 1 µC=e, so the fraction removed is (1 µC=e) (1 g=m p) = 10!6 C " "10!24 g 1 ...

Physics Tutorial: GroundingGrounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of electrons between the charged object and a ground. A ground is simply an object that serves as a seemingly infinite reservoir of electrons; the ground is ...
