Question:

1. in a hydraulic lift, the diameters of the pistons are 5.00cm and 20.0cm, respectively a car weighing w10.0kN is to be lifted by the force of the large piston? a. what force F must be applied to the small piston?b. when the small piston is pushed in by 10.0cm, how far is the car lifted?c. what is the increase in the pressure of the fluid?can you please show me how to do this. need help i have an exam tommarrow and i dont know how to do this. please helpppppppp

Slow down and downshift, then use more rear brake. Stay out of the center part of the lane your in, that's where most of the oil build up is. Apply front brakes with light touch, a lot of the water being picked up off the road will have oil mixed in with it coating your brake rotors. This causes them to slip at first then get real sticky. If you lock up the front wheel get ready to get high-sided!!
I balance between front and rear (prevent locking up), and always slow down quite a bit at the first sign of rain
I don't know the break system on your scooter but with mine I would slowly press down on the back break to slow down, then slowly go down on the front. Don't ever lock up your breaks, meaning squeezing it to full right away. And don't break too fast in the rain or you will slide. Which also means you should drive slower in the rain and further back from the person in front of you.

a) assuming the car is already lifted a bit and the mass of the hydraulic fuid and the cylinders and friction/viscosity are negligible then (5/20)^2 *10000 N is needed to move the small cylinder. b) (5/20)^2*10 cm c) there is no increase in the pressure of the fluid if the car was already lifted a bit - hm - maybe the piston was just touching the car - that can't be right though, how many cars have 10cm travel in the suspension? - o.k. assuming the car is on a lift (which has negligible mass compared with the car) then 10kN force is applied over pi*.01 square metres area , about 3. 18 MN/m^2 3.18MPa
