A capillary tube of internal diameter 0.21mm is dipped intoba liquid whose density is 0.79g cm^-3. The liquid rises in thus capillary to a height of 6.30cm calculate the surface tension of the liquid?

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
