In the process of changing a flat tire, a motorist uses a hydraulic jack. she begins by applying a force of 64 n to the input piston, which has a radius r1. as a result, the output plunger, which has a radius r2, applies a force to the car. the ratio r2/r1 has a value of 9.3. ignore the height difference between the input piston and output plunger and determine the force that the output plunger applies to the car.

The force that the output plunger applies to the car is: 5535 N.

Explanation:

We need to remember the equation that relate force and pressure is:. Now we want to determine the force applied to the car, so taking acount that the difference in height of input piston with the output plunger is neglected, we can get: and solving for the F2:, replacing the values given we obtain the force as:

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
