An electron is accelerated inside a parallel plate capacitor. the electron leaves the negative plate with a negligible initial velocity and then after the acceleration it hits the positive plate with a final velocity β. the distance between the plates is 14.1 cm, and the voltage difference is 142 kv. determine the final velocity β of the electron using classical mechanics. (the rest mass of the electron is 9.11 x 10^-31 kg, the rest energy of the electron is 511 kev.) what is the final velocity β of the electron if you use relativistic mechanics?

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
