Nasa launches rockets eastward from cape canaveral to get a free velocity boost from the earth's rotation. if the earth's radius is 6371.0 km, the earth's mass is 5.97237x104 kg, the international space station is 400 km above the ground, and cape canaveral is 28 n of the equator, a) what is the earth's rotational speed at the equator (in km/h)? b) what is the orbital speed of the iss (in km/h)? what percent of their needed velocity do rockets get from being launched east at cape canaveral?

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?
