Two glasses capillary tube of diameter 0.05mm and 2.00mm are dipped in a pool of water. How high will the water rise in each of the tubes?​

Explanation:

The height h through which a liquid will rise in a capillary tube of radius r is given by

h=

rρg

2Scosθ

, where S is the surface tension, ρ is the density of the liquid and θ is the angle of contact.

explanation:

because they are cartillidge

because if the tool that you are using is not balanced it there would be false mass.
