An external pressure applied to an enclosed fluid in a hydraulic lift. piston 1 has a radius that is 1/200 the radius of piston 2 (r1 = r2/200). if the bottom of both pistons start from the same vertical height, how much force needs to by applied to the first piston in order to begin lifting a weight of 20,000 n positioned atop the second piston?

0.5 N

Explanation:

= radius of piston 1

= radius of piston 2

Given that :

= Force applied on piston 1

= Force applied on piston 2 = Weight being lifted = 20000 N

Using pascal's law

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

less than one you can't create energy
