4.The radius of the earth is 6.37 × 〖10〗^6 m, and its mass is 5.98 × 〖10〗^24 kg.
a.) Find the average density of the earth
b.) The average density of the rocks at the earth’s surface 2.7 × 〖10〗^(3 ) kg. What must be true of the earth’s interior is composed? Is it likely that the earth is hollow and peopled by another species, as ancients believed?
5.Accomplished silver waters in India can pound silver into incredibly thin sheets, as thin as 3.00 × 〖10〗^(-7) m. Find the area of such a sheet that can be formed from 1.0 kg silver.
6.The density of concrete is 2.3 ×〖10〗^3 kg/m^3. On this basis how many tons of concrete will be required to build a wall 6 meters long, 2.5 meters high and 20 cm thick?
7.A sphere of granite is 2 meters in diameter. How much does the sphere weight if the density of granite is 2.9 × 〖10〗^3 kg/m^3.
Please HELP ME...even with just one problem
thank you in advance
