A cubic block of mass m and side b is placed on a smooth floor. A smooth and rigid rod of length L and with negligible mass is leaning against the block. A sphere of mass M is attached to the upper end of rod. The lower end of the rod is fixed at point O, but it can rotate freely around the point in the vertical plane. Initially the angle between the rod and the floor is αα while the system is at rest. After releasing, find the speed of the block when the angle between rod and the floor is β.

Working in a laboratory, you carefully measure 80.00 mL of solution ten times in a row, each time adding it to a flask. Your supervisor then measure the total; there's 900.0 mL in the flask. You redo the entire procedure, and again the total is.900.0 mL. Your measurements were: O Inaccurate O Imprecise O Perfect O Inaccurate and imprecise W
When you are swimming at the bottom of a pool, the water above and around you exerts force on your eardrum. Calculate the force (in N) exerted on your eardrum when you are at the bottom of a pool that is 5.0 m deep. Assume that the area of your eardrum is 1 cm^2 and the density of water is 1000 kg/m^3 (10,000 cm^2 = 1m^2) (Ans: 5N) To solve this, which of the following equation/s should you use (check as many that best applies) O Q = mL O F1_ F2 A1 A2 O F=ma O A1V1= A2V2 O fEdA = denc €0 Ο ΔL αLo Δ .
