If the bed has a counterclockwise angular acceleration of 0.2rad/s2, what is the magnitude of the force exerted on the bed at B by the hydraulic cylinder

Modern atomic theory states that the atom is a diffuse cloud of surrounding a small, dense nucleus. a) electron b) neutron c) proton d) quark eliminate

Which articulations allow for greatest range of motion?

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?
