A tank initially holds 100 gal of a brine solution containing 20 lb of salt. At t = 0, fresh water is poured into the tank at the rate of 5 gal/min, while the well-stirred mixture leaves the tank at the same rate. Find the amount of salt x in the tank (in lbs) at any time 1 (in minutes). A) x = 20e B) x = 20e 10 C) x = 20e D) x = 20e

Help with the questions: 1- Continuity tells us that whatever the volume of fluid in a pipe passing a particular point per second, the same volume must pass every other point in a second. The fluid is not accumulating or vanishing along the way. A) True B) False 2- When a fluid moves from a wider area of a pipe to a narrower one, its speed increases. A) True B) False 3- A fluid exerts a net upward force on any object it surrounds, called the buoyant force. A) True B) False
