At 55 mph, under good conditions, your vehicle will travel about feet in the time that it takes you to react to an object in your path and bring your vehicle to a complete stop.

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 = 2.1 m below the tank bottom which is a = 7.4 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)

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
