Astress of 13.72 mpa is applied in the [001] direction of a unit cell of an fcc copper single-crystal. calculate the resolved shear stress on the plane in the [ 0 1 ¯ 1 ] direction. (this is the same as 7.4 just in a different direction with a different load). give the answer in mpa with 2 decimals of accuracy.

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

The slope of a velocity time graph over any interval of time gives the during that interval

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
