In a hydraulic garage lift, the small piston has a radius of 4.0 cm and the large piston has a radius of 20 cm. what force must be applied on the small piston in order to lift a car weighing 20,000 n on the large piston? assume the pistons each have negligible weight.

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.
