Aproton is released from rest at the positive plate of a parallelplatecapacitor. it crosses the capacitor and reaches the negativeplate with a speed of 50,000 m/s. what will be the final speed ofan electron released from rest at the negative plate

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

Which of the following represents an upside-down image?

If element x has 99 protons how many electrons does it have
