The basic function of an automobile's carburetor is to atomize the gasoline and mix it with air to promote rapid combustion.Assume that 40 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) 60,000 cm² B) 24,000 cm² C) 20,000 cm² D) 2800 cm²

The total surface area of the droplets is given by:$$4\pi r^2N$$where r is the radius of each droplet and N is the number of droplets.Substituting the given values, we get:$$4\pi (2.0 	imes 10^{-5} 	ext{ m})^2N = 60,000 	ext{ cm}^2$$Therefore, the total surface area of the droplets is 60,000 cm^2.
