A car jack has a pump piston with radius R1=0.16m and a resultant piston with radius R2=0.10m. The combined weight of the car and the plunger is W=1500N. Assume that the height of the piston and plunger are the same. How much force is required on the pump piston to keep the car in equilibrium?

Blood pressure the total amount of blood the heart pumps in one minute 2. cardiac output the number of times your heart beats in a minute 3. dilate the amount of blood that the heart can pump in a single beat 4. heart rate the force exerted on the walls of the blood vessels by the blood that moves through them 5. stroke volume to widen or get larger in size
