•• cp two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. block aa has mass 15.0 kg, and block bb has mass mm. a constant horizontal force f=60.0 nf=60.0 n is applied to block aa (fig. p4.38). in the first 5.00 s after the force is applied, block aa moves 18.0 m to the right. (a) while the blocks are moving, what is the tension tt in the rope that connects the two blocks? (b) what is the mass of block b?

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?
