Replace the two forces acting on the frame by a wrench. Write both the force R and the moment M of the wrench as vectors and specify the coordinates of the point P in the y-z plane through which the line of action of the wrench passes. Note that the force of magnitude 200 N is parallel to the x-axis.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
