Homework Answers
1- air pressure is greatest at sea level and falls with increasing altitude. Denver is at high altitude than Tallahassee so ------TRUE
2- buoyant force always acts upwards, Since it has lost weight equal to fluid displaced so buoyant force acts on it. -----------UP

I need help on how to find the atmospheric pressure from the
scatter plot and trend line I made with the results from my Boyle's
Law lab. I don't know if my scatter plot is correct. I need the
atmospheric pressure in order to fill in Table 5 and answer some
questions.
24. Use the data in Data Table 1 and Data Table 3 to create a
scatter-plot graph of 1/Average Volume vs. Pressure; with
“1/Average Volume (mL-1)” on the...

13. A 119 g mass is attached to the end of an unstressed vertical spring (of constant 52.5 N/m) and then dropped. The acceleration of gravity is 9.8 m/s2 What is its maximum speed? Correct answer: 0.466573 m/s. 14. A(n) 60.3 g ball is dropped from a height of 53.7 cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement...

Part B-Fluids Attempt any two of the following three problems Evangelista Torricelli (1608-1647) was the first to put forward the idea that we live at the bottom of an ocean of air. Given the value of atmospheric pressure at the surface of the Earth, and the fact that there is zero pressure in the vacuum of space, determine the depth of the atmosphere, assuming that the density of air and the acceleration of gravity are...

The air pressure outside the tank is atmospheric(Patm 1,013 x10s N/m2) and the absolute pressure inside the tank at the top is 1.4 x 10s Pa with the hole being 2.7 m below the level of the acid in the tank. What velocity will the acid exit the tank through the hole?...

PRACTICE IT Use the worked example above to help you solve this problem. A block with mass m 4.30 kg and a ball with mass m2 = 7.50 kg are connected by a light string that passes over a frictionless pulley, as shown in figure (a). The coefficient of kinetic friction between the block and the surface is 0.300. (a) Find the acceleration of the two objects and the tension in the string. a= 5.16...
