correct!
the questions is incomplete.
incomplete but if the rest of the questions is "... by a light vertical string of length 1m. calculate the maximum inclination of the string to the vertical" Then the answer is: Conservation of linear momentum applies to the embedding process. Use that to
density of water = 1 gram/cm^3 1. weight in water is 0 2.volume = 100 cm^3 because it displaced 100 grams of water Therefore if neutrally buoyant it weights 100 grams in air. 3. Buoyant force = 100 grams . That was given. 4. volume = 100 cm^2 as we said
4(cosx)^2 - 3 = 0 Add 3 to each side 4(cosx)^2 = 3 Divide both sides by 4 (cosx)^2 = 3/4 Take the square root of each side cosx = sqrt(3/4) or -sqrt(3/4) cosx = sqrt(3)/2 or -sqrt(3)/2 x = pi/6, 11pi/6 or 5pi/6, 7pi/6 :)
I will assume that you have Cost numbers in column A, Sales numbers in column B. Try this formula in cell C1: =if(B1>=1.2*A1, 0.06*B1,"")
