The michelson-morley experiment showed that the speed of light varies depending on the direction of the ether wind. true false

false

Explanation:

Hi, The Michelson-Morley experiment was designed to measure the extra time it took a light beam to travel "there-and-back" against the ether wind, compared to a light beam travelling "sideways across" the ether wind.

The experiment failed, there was no variation, and years later Einstein explained that there is no ether. Light is a special sort of wave which requires no medium to carry it.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
