Water rises to a height of 5 cm in a certain glass capillary tube. In the same tube the level of mercury surface is depressed by 1.54cm. Compare the surface tensions of water and mercury. Specific weight of Mercury is 13.6 x10^3 Kg/m^3 and that of water is 10^3 Kg/m^3. Angle of contact of glass with mercury and water is 130 degree and 0 degree, respectively.

  • " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
