Suppose we are driving, and in 1 second, we steadily increase our velocity from 30 kilometers per hour to 35 kilometers per hour, and then to 40 kilometers per hour in the next second to 45 in the next second, and so on. We change our velocity by 5 km per hour each second. This change in velocity is what we mean by acceleration

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Your town is considering building a biodiesel power plant describe at least two advantages and two disadvantages

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?
