Along thin rod of mass m and length l is situated along the y axis with one end at the origin. a small spherical mass m1 is placed at the location p, which is at a distance d from the origin.

if l = 2.00 ? 104 m, d = 18.0 ? 104 m, m = 14.0 ? 106 kg, and m1 = 8.00 ? 106 kg, what is the value of this potential energy?

The vapour pressure of benzene is 53.3 kpa at 60.6 °c, but it fell to 51.5 kpa when 19.0 g of a non-volatile organic compound was dissolved in 500 g of benzene. calculate the molar mass of the compound.
