Acurrent of 16.0 ma is maintained in a single circular loop of 1.90 m circumference. a magnetic field of 0.790 t is directed parallel to the plane of the loop.(a) calculate the magnetic moment of the loop. ma · m2(b) what is the magnitude of the torque exerted by the magnetic field on the loop? mn · m

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

What is the coefficient of kinetic friction μk between the block and the tabletop?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
