A metal surface is illuminated by light with a wavelength of 500 nm .The maximum kinetic energy of the emitted electrons is found to be 1.30 eV. What is the maximum electron kinetic energy if the same metal is illuminated by light with a wavelength of 400 nm?

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

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
