What was galileo’s contribution to the study of motion?

Hello! :)

A study of motion is basically like physics.

Hence, using the telescope, Galileo discovered the mountains on the moon, the spots on the sun, and four moons of Jupiter. His discoveries provided the evidence to support the theory that the earth and other planets revolved around the sun.

Hope this helped and I hope I answered in time!

Good luck!

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
