2. Electrons are accelerated in the picture tube of a-television through a po- tential difference of 8.00 x 10^3 V. (Use the values q e=1.60 x 10^-19
kg and
m e = 9.109 x 10^-31 kg.)
a. What is the change in the potential energy of each electron traveling
in this tube?
b. What is the change in the kinetic energy of the electrons?
c. At what speed do the electrons hit the screen?
(Please help !!)

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
