To work out the units on your own, simply solve the equation with just units. S = kg/m 3 * m * m/s 2 * m. Two of the meter units cancel out two of the per meter units and you are left with 1 kg-m/s 2 /m or 1 N/m. 3. WebApr 7, 2024 · The negative oxygen atom is attracted to the positive hydrogen atom, so the molecules stick together. This grouping forms surface tension. Pennies have a small ridge around it.
