If circumference C = 2 pi r where r is the radius, how long would it take a car to travel once around a circular track with a 80 meter radius if it is traveling 50 m/s ?

What is a possible result of higher air temperature caused by global warming

Properties seen when one one substance changes to another are known as properties

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
