the ultraviolet region of the electromagnetic spectrum extends beyond violet in the visible region. knowing the relationship between wavelength and frequency, predict how the frequency of ultraviolet radiation compares to that of visible light. explain how you came to your conclusion.

Suppose that three astronomical objects, 1, 2, and 3 are observed to lie on a line, and the distance from object 1 to object 3 is d. object 1 has four times the mass of object 3, and seven times the mass of object 2. find the distance between objects 1 and 2 for which the net force on object 2 is zero.
