There are molecules present in every liquid. Attachment of these molecules with each other gives rise to surface tension. It is the result of intermolecular forces. It is due to surface tension the insects float on a liquid.
The water has the highest surface tension. it is because molecules present on the surface of the water are held together by very strong hydrogen bonds. There is high attraction among the molecules of water.
Here you are looking on the Free Body diagram of a net force of 0N in both the x and y-directions. the only ones that has that condition met is A and C.
A common method of experimentation that is used to collect data on hypotheses of end up causing-effect is a contrast between two groups.
One community, the experimental group, is receiving medication for having any result. Some other group becomes left exposed, the control group, whether creating a different treatment.
