The diameter of the output piston is 17 cm, and the input force is 340 N What is the area of the input piston? Express your answer using two significant figures. A 3.5. 103 m2 Submit X Incorrect; Try Again; 3 attempts remaining Part B What is the work done in lifting the car 43 cm?Explanation / Answer
by pascal's law
input pressure = output pressure
input force/ input area = output force/output area
340/input area = 940 x 9.81 / ( pi doutput2 /4)
input area = 8.368 x 10-4 m2
