The basic function of an automobile's carburetor is to atomize the gasoline and mix it with air to promote rapid combustion.Assume that 30 cm³ of gasoline is atomized into N spherical droplets.Each droplet has a radius of 2.0 ´ 10^-5 m.Find the total surface area of these N spherical droplets. A)2 100 cm² B)15 000 cm² C)18 000 cm² D)45 000 cm²

Quizplus · Accepted Answer

First, calculate the volume of one droplet using the formula for the volume of a sphere: V = (4/3)πr³. Then, find N by dividing the total volume of gasoline by the volume of one droplet. Finally, calculate the total surface area using the formula for the surface area of a sphere: A = 4πr², and multiply by N.
