Atank is filled with 1000 liters of pure water. brine containing 0.07 kg of salt per liter enters the tank at 7 liters per minute. another brine solution containing 0.03 kg of salt per liter enters the tank at 10 liters per minute. the contents of the tank are kept thoroughly mixed and the drains from the tank at 17 liters per minute.

a. determine the differential equation which describes this system. let s(t)denote the number of kg of salt in the tank after t minutes. then

Will a heavier bowling ball hit pins better than a lighter bsll

What are similarities and differences between refraction, reflection, diffraction and absorption?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
