Concept explainers
An American press release describing the 1986 nonstop, round-the-world trip by the ultra-lightweight aircraft Voyager included the following data:
flight distance: 25,012 mi
fight time: 9 days, 3 minute, 44 seconds
fuel capacity: nearly 9000 lb
fuel remaining at end of fight: 14 gal
To the maximum number of significant figures permitted, calculate
a. the average speed of the aircraft in kilometers per hour
b. fie fuel consumption kilometers per kilogram of fuel (assume density of 0.70 g/ mL, for the fuel)

- A high-‐speed chase captured on a surveillance camera showed the suspect running a red light at an The suspect vehicle collided with a vehicle that had just turned into the path of his car. The tape shows that it took the car 0.546 s to cross the intersection, which was measured to be 41.2 ft. The posted speed limit was 25 mph. Determine whether the suspect was speeding at the moment he collided with the second vehicle.arrow_forwardChemistry A student performed the same experiment as you.

- One gallon of gasoline in an automobile’s engine produces on the average 9.5 kg of carbon dioxide, which is a greenhouse gas, that’s is, it promotes the warming of Earth’s atmosphere. Calculate the annual production of carbon dioxide in kilograms if the are 250 million cars in the United States and each car covers a distance of 5000 mi at a consumption rate of 20 miles per gallon.arrow_forwardAn experiment with a pycnometer resulted in the following data: Mass of Pycnomter = 25.428 g Mass of Pycnometer filled with water = 44.021 grams Mass of Pycnometer filled with liquid X = 41.421 grams a) What is the specific gravity of liquid X? b) If methanol (Specific Gravity = 0.790) was used rather than water in measuring the density of irregular objects, how would that affect the result? Why?arrow_forwardWhat is the average speed of a cheetah that runs 88 m in 5 seconds? a) In m/s . b) . In miles/hour?

- A gasoline station in Manila, Philippines, charges 38.46 pesos per liter of unleaded gasoline at a time when one US. dollar (USD) buys 47.15 pesos (PHP). The car you are driving has a gas tank with a capacity of 14 U.S. gallons and gets 24 miles per gallon. (a) What is the cost of unleaded gasoline in Manila in USD per gallon? (b) How much would a tankful of unleaded gasoline for your car cost in USD? (c) Suppose that you have only PHP 1255 (a day's wage for an elementary school teacher) and the car's tank is almost empty. How many miles can you expect to drive if you spend all your money on gasoline?arrow_forwardA thief plans to steal a bar of gold from a womans purse and replace it with a bag of sand.
