Consider two forces F1 and F2 of magnitudes 5N each pulling at an object lying at the origin. F1 is directed along the X-axis, whereas F2 is directed along Y-axis. Determine the resultant force (magnitude and direction) experienced by the object.

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?
