If the density of mercury is 13.6g/c.c. and the angles of contact for mercury and water are 135 degree and 0 degree respectively, the ratio of surface tension for water and mercury is

Water rises to a height of 10cm in a capillary tube and mercury falls to a depth of 3.42 cm in the same capillary tube. If the density of mercury is 13.6g/c.c. and the angles of contact for mercury and water are 135 degree and 0 degree respectively, the ratio of surface tension for water and mercury is

then what will be the new terminal velocity ? Two identical water drops are falling down in the air with a terminal velocity v. If the two drops combine and from a single drop
