How much work can an engine do in 15 minutes if it generates 22 MW of power and has a mass of 330 kg? *

The dominant wavelength of energy emitted by the sun is

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength

If we compare the force of gravity to strong nuclear force, we could conclude that
