50 (1 point) The density of oil in a circular oil slick on the surface of the ocean at a distance of r meters from the center of the slick is given by S(r) = 10 kilograms per square meter. Find the exact value of the 1 + p2 mass of the oil slick if the slick extends from r = 0 to r = 4 meters. Mass = Include units in your answer.
A circular oil slick is expanding with radius, r in yards, at time t in hours given by r=2t-0.1t^2, for t in hours, 0<t<10. find a formula for the area in square yards, A= F(t), as a function of time.

Problem 18.87 Drops of an oil that has a mass density of 700 kg/m are released from a broken undersea oil pipe that is 1300 m below the ocean surface. Use 1000 kg/m for the mass density of ocean water Part A If the drops have an average diameter of 100 m, how long do they take to rise to the surface? Hint. The drops quickly reach terminal speed and experience a viscous drag force of magnitude F (0.0200 Pa...
