Question 4 10 pts Brian is on Mars and decides to dump his physics textbook into this never before seen hydrocarbon lake. The atmospheric pressure in Mars is 1/4 that of Earth's and the gravitational acceleration is 3m/s^2. The hydrocarbon liquid has a density of 1300 kg/m^3. If the book is experiencing a force of 426 N underneath the lake, how deep is the book inside the lake? The book has a surface area of 6.4x10^-3 m^2. Round answer to...

2. Muscle can generate approximately 90 N of force per square centimeter of cross-sectional area. If a biceps brachii has a cross-sectional area of 10 cm2, how much force can it exert? ANSWER FOR PROBLEM 2 = 900 N 3. Using the same force/cross-sectional area estimate as in Problem 2, and estimating the cross sectional area of your own biceps brachii how much force should the muscle be able to produce
