- The area of the piston to the master cylinder in a hydraulic braking system of a car is 0.7 square inches. If a force of 5.4 lb is applied to this piston, what is the force on the brake pad of one wheel if the area of the pad is 1.9 square inches? (Hint: Since the force on each of the four wheels would be the same, you only need to calculate the force on one.)arrow_forwardPlease answer as much as you can! Thank you in advance! A beachball has a diameter of 24 cm and weighs about 6N. A-What is the volume of the beachball? Then, use this number to calculate the beachball’s average density in kg m-3. B-What is the volume of water displaced by the beachball if it is in the pool? C- Now, using a rope, you tie the beachball to the bottom of the pool so only half of the ball is submerged. What would the diagram look like? D- What is the buoyant force of the tethered beachball? What is the tension on the rope?arrow_forward(next question) Based on the problem answered (as shown in the photo) The data are the same as in the previous example.
