6.) A hydraulic lift is used to raise a car. The piston has a surface area of 1 square meter. The
pressure needed to lift the car is 20000 N per square meter. What is the weight of the car? Hint:
solve for force since weight is a force.

14,500

Explanation:

) The Titanic was found in 1985 lying at the bottom of the North Atlantic at ... (Use density of water= 1000 kg/m3) ... Floating at the surface means the weight of the ice equals the buoyant force. ... 6) To inspect a 14,500 N car, it is raised with a hydraulic lift. ... air on the wing, of about 2000 N per square meter of wing area.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
