Andre, a physics undergraduate, enters a coffee shop that is holding a contest, Customers who guess the number of coffee beans inside of a closed, 20.0 fl oz aluminum commuter mug get a free pastry and an espresso drink. Motivated by the prospect of free food and coffee, Andre puts his finely-tuned estimation skills to work. Andre assumes that a typical coffee bean is about 1 cm long, Based on that assumption, what should Andre submit as his estimate for the number of coffee beans in the mug? estimate: coffee beans

In the following scenario, identify which of the statements represents a theory, law, or hypothesis. (a) A student exploring the properties of gases proposes that is she decreases the volume of a sample of gas then the pressure exerted by the sample will increase (b) Many scientists over time have conducted similar experiments and have concluded that pressure and volume are inversely proportional. (c) She proposes that the reason this occurs is that if the volume is decreased, more molecules will collide with a given area of the container walls, causing the pressure to be greater.
As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffic looks like this. At what lime(s) does the highest number of cars pass through the intersection? At what time(s) does the lowest number of cars pass through the intersection? Briefly describe the trend in numbers of cars over the course of the day. Provide a hypothesis explaining the trend in numbers of cars over the course of the day. Provide a possible experiment that could test your hypothesis.
In Active Example 3-29 you calculated that you would have to work six weeks to earn enough money to buy a 1082.49 television. You would be working five shifts of four hours each at 9.25/hr. But, alas, when you received your first pay check, you found that exactly 23 of your earnings had been withheld for social security, federal and state income taxes, and workers compensation insurance. Taking these into account, how many weeks will it take to earn the 1082.49?
The main weapon on a military tank is a cannon that fires a blunt projectile specially designed to cause a shock wave when it hits another tank. The projectile fits into a finned casing that improves its accuracy. Calculate the mass of the projectile, assuming it is a cylinder of uranium (density = 19.05 g/cm3) that is 105 mm in diameter and 30 cm in height. The volume of a cylinder is given by the equation V = r2h

Dashboard My Home OWLV2 | Online teaching and learning resource from Cengag [References) A student gently drops an object weighing 15.7 g into an open vessel that is full of ethanol, so that a volume of ethanol spills out equal to the volume of the object. The experimenter now finds that the vessel and its contents weigh 10.6 g more than the vessel full of ethanol only. The density of ethanol is 0.789 g/cm°. What is the density of the object?

Chemistry There are 2.55 1015 short tons of oxygen in the atmosphere (1 short ton = 2000 lb). How many metric tons (T) of oxygen are present in the atmosphere (1 metric ton = 1000 kg)? %3D 10 T (Enter your answer in scientific notation.)
Gold can be hammered into extremely thin sheets called gold leaf. A 200-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft x 1.0 ft. %3D What is the average thickness of the sheet in meters? Hints: Calculate the volume of the sheet from its density and mass, and then use the volume relationship for a rectangular solid, V = length x width x thickness.
An atom of helium has a radius He = 31. pm and an average speed in the gas phase at 25°C of 787.m/s. Suppose the speed of a helium atom at 25°C has been measured to within 0.10%. Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of I and round it to 2 significant figures. For example, if the smallest box the atom could be in turns He out to be 42.0 times the radius of an atom of helium, you would enter "42.1" as your answer. esc 0₁ F He Continue 55°F Clear ♫x F1 !

I think I did a calculation wrong but I am having trouble understanding significant figures. In this problem, I am calculation the density of water from my previous calculations mass= 7.359g and volume=7.8mL. So I then divided 7.359g by 7.8mL to find density and got (.9434615385) on my calculator which I then turned into (.94) because I believe there should be 2 significant figures. Is (.94) correct or should 1.4 be the final answer?
