Mercury has an angle of contact equal to 140° with glass. A nomor tube of
glass of radius imm is dipped in a trough of mercury. By what amount does
the mercury dip down in the tube relative to the liquid surface outside?
Surface tension of mercury at the temperature of the experiment is 0.465
Density of moreury - 136 * 10% ugm3 & g = 9.8mg-2

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

it is called kinetic energy
