Aforce of 500 n is applied to a hydraulic jack piston that is 0.2 m in diameter. if the piston that supports the load has a diameter of 2.0 m, approximately how much mass can be lifted by the jack? ignore any difference in height between the pistons.

50,000 N

Explanation:

d = 0.2 m, r = 0.1 m,  f = 500 N,

D = 2 m, R = 1 m

Let F be the weight lifted by the jack.

By use of Pascal's law

f/a = F / A

F = f x A / a

F = 500 x 3.14 x 1 x 1 / (3.14 x 0.1 x 0.1)

F = 50,000 N

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

connectedness in handwriting analysis is a useful tool in establishing the writer’s method of thinking and its perception in where he/she fits in to the environment around him in the social sense. in addition, the more connected the writing of an individual, the more he/she is flexible and single minded.
