An electron is trapped between two large parallel charged plates of a capacitive system. The plates are separated by a distance of 1 cm, and there is a vacuum in the region between the plates. The electron is initially found midway between the plates with a kinetic energy of 10 eV and with its velocity directed toward the negative plate. How far towards the negative plate will the electron get if the potential difference between the plates is 100 V? (1 eV = 1.602 x 10-19 J)

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

Who was the first scientist to measure speed as distance over time?

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?
