What is the resistance of a circuit 25 volts are used to push a current of 5 A through a wire.

The speed of light can be used to measure the

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
