Hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

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?

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
