With what speed do the electrons strike the screen? hint: the kinetic energy of an electron which has been accelerated through a potential difference of 1 v has a kinetic energy equal to 1 ev.

If the wheels lock when braking suddenly the vehicle: a: loses traction b: lose steering wheel ability c: gain speed slightly d: gain steering ability

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
