The sample space of equally likely outcomes for the experiment of rolling two fair dice is :
Diffraction studies of crystals depend on interferences between planes of electron density, whose spacing must be greater than the wavelength. Since the shortest bonds are about 0.1 nm, such planes are unlikely to be closer than 0.1 nm.
A single conducting loop of wire has an area of .2 x 10^-2 m^2 and a resistant of 110O. Perpendicular to the plan of the loop is a magnetic field of strength .48 T at what rate ( in T/s) must this field change if the induced current in the loop is
