In a television tube, electrons travel down the tube and strike the fluorescent material at the end of the tube. Their impact with this material causes light to be emitted, thereby producing the picture we see. The electrons are accelerated from rest to a speed of 2 x 10^8 m/s in a distance of 1.50 cm.
What is the acceleration of an electron during this process?
suppose the apparatus as used in this lab: A cube of mass M = 500 g and side length 30 mm is free to spin on an axis through the center of one face. A massless pulley on this axis has a diameter of 2r = 10 mm. An object with m = 50 g is hung from ..
