Answer: 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.
20,83 m / s (metros por segundo)
divide 10 metros entre 8 minutos y obtén 20.83333333
20.83 m/s (meters per second)
divide 10 meters by 8 minutes and get 20.83333333
Answer:
A. They travel faster in a solid than other mediums
Explanation:
Sound waves travel faster in solids because the density of solids is higher than that of liquids which means that the particles are closer together and sound can be transmitted more easily.
3. 2 meters per second 4. i think object 7. i’ll try to figure it out 8. .77 9. 25km 10. 10m each second
