You have an 18-carat gold coin (an alloy of gold and copper). Its mass is 6 grams. Using the fact that the number of carats is equal to (24*mass of gold/total mass), calculate the volume of gold in the coin. (density of pure gold = 19300 kg/m3, density of copper = 8960 kg/m3.) a.) 1.68*10-7 m3 b) 2.33*10-7 m3                c) 4*10-7 m3.   In the problem above, what is the density of the coin? a.) 14963 kg/m3 b) 12333 kg/m3                c) 19300 kg/m3

dV An oil tanker aground on a reef is forming a circular oil slick about 0.1 foot thick. To estimate the rate (in cubic feet per minute) at which the oil is leaking from the tanker, it was found that the radius of the slick was increasing at 0.31 foot dt dR dV per minute (- = 0.31) when the radius R was 400 feet. Find using T 3.14. dt dt Tanker A=TR? V=0.1A R dV ft3 /min dt (Type an integer or a decimal. Round to the nearest whole number as needed.)
