Water leaks out of a tank through a square hole with 3-inch sides. at time t (in seconds) the velocity of water flowing through the hole is v ft/sec (where v is a function of time, t). write a definite integral that represents the total amount of water (in cubic feet) lost in the first minute.

The difference between two numbers is 15. when twice the smaller number is subtracted from three times the larger number, the difference is 58.what is the larger number?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
