A 75ft diagnol brace on a bridge connects a support of the center of the bridge The horizontal distance that it spans is 15ft longer than the hieght that reaches on the side of the bridge.Find the horizontal and vertical distance spanned by this brace
Does that give me a negative velocity?
A boy throws a stone vertically up to a man standing at a heigt of 2 m above the boy. Of the stone is thrown up with a velocity of 7.0m s what is the velocity of the stone at the instant when it is caught by the man. A clear explaination is greatly appreciated
Because like dissolves like. Oil is a nonpolar molecule which then is the same as sugar. They are both nonpolar.
m=12grams Molar Mass= 180.18 V=.1L n= m/MM= 0.067 moles. Molarity= n/V= .067/.1= .67 M1V1=M2V2 => 0.67(.05)=M2(.5) Solve for M2 and you get .067 M= m/VMM : Molarty= mass/ Volume x Molar Mass so m= MVMM : mass= Molarity x Volume x Molar Mass m= .067(.1)(180.18)= 1.21 Just th...
