- A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a 240-g rock 89.0 cm3 of water? (Note that the accuracy and practical applications of this technique are more limited than a variety of others that are based on Archimedes' principle.)Suppose you have a coffee with a circular cross-section and vertical sides (uniform radius). What is its inside radius if it holds 375 g of coffee filled to a depth of 7.50 cm? Assume coffee has the same density as water.A certain hydraulic system is designed to exert a force 100 times as large as the put into it. (a) What must be the ratio of the area of the cylinder that is being controlled to area of the master cylinder? (b) What must be the ratio of their diameters? (c) By what factor is the distance through which the output force moves reduced relative to the distance through which input force moves? Assume no losses due to friction.
- A rectangular gasoline tank bold 30.0 kg of gasoline when full. What is the depth of the tank if is 0.500-m wide by 0.900-m long? (b) Discuss whether gas tank has a reasonable volume for a passenger car.Check Your Understanding Figure 1.4 says the mass of the atmosphere is 1019kg . Assuming the density of the atmosphere is 1kg/m3 , estimate the height of Earth’s atmosphere. Do you think your answer is an underestimate or an overestimate? Explain why. How many piano tuners are there in New York City? How many leaves are on that tree? If you are studying photosynthesis or thinking of writing a smartphone app tot piano tuners, then the answers to these questions might be of great interest to you. Otherwise, you probably couldn’t care less what the answers are. However, these are exactly the soils of estimation problems that people in various tech industries have been asking potential employees to evaluate their quantitative reasoning skills. If building physical intuition and evaluating quantitative claims do not seem like sufficient reasons tot you to practice estimation problems, how about the fact that being good at them just might land you a high-paying job? For practice estimating relative lengths, areas, and volumes, check out this PhET (https://openstaxcollege.org/l/21lengthgame) simulation, titled “Estimation.”The average density of the Sun is on the order 103kg/m3 . (a) Estimate the diameter of the Sun. (b) Given that the Sun subtends at an angle of about half a degree in the sky, estimate its distance from Earth.
- A beer cylindrical barrel has a mass of 12Kg with an inside length twice its inside diameter of 69cm. Assuming the density of beer is 950Kg/m³, determine the total mass and weight of the barrel when filled with beer.A solid with a cylindrical shape has a radius of 5cm ang height of 10cm. What is the density of the solid if its mass is 200 grams?How many minutes does IH take to fll a 36 gallon bathtub if the faucet opening has an area of 1.2 cm2 and water flows out of it at 3.2 mis? li gal = 3.785 L = 3.185 x103 m³)
