Is surface tension a vector?

When a 'U' shaped slider of negligible mass is dipped in a soap solution and lifted, a thin film of soap is formed in the frame. It supports a weight of 2.0 x 10${}^{-2}$ N. If the length of the slider is 40cm, the surface tension of the film of soap is:

A certain number of spherical drops of a liquid of radius r coalesce to form a single drop of radius R and volume V. If T is the surface tension of the liquid, then

The sap in trees, which consists mainly of water in summer, rises in a system of capillaries of radius $r=2.5\times 10^{-5}m$. The surface tension of sap is $T=7.28\times 10^{-2}N{m}^{-1}$ and the angle of contact is $0^{\circ }$. Does surface tension alone account for the supply of water to the top of all trees?

The surface tension of water is $7\times 10^{-2}N/m.$ The weight of water supported by surface tension in a capillary tube of 0.1 mm radius, will be __________.

In a surface tension experiment with a capillary tube water rises upto $0.1m$ If the same experiment repeated in an artificial satellite which is revolving around the earth water will rise in the capillary tube upto a height of

A drop of mercury of radius $2mm$ is split into $8$ identical drops. Find the increase in surface energy. Surface tension of mercury $=0.465J{m}^{-2}$

Two mercury droplets of radii $0.1cm$ and $0.2cm$ collapse into one single drop. What amount of energy is released/ absorbed? The surface tension of mercury $T=435.5\times 10^{-3}N{m}^{-1}$.

A container, whose bottom has around holes with diameter $0.1mm$ is filled with water. The maximum height in cm upto which water can be filled without leakage will be ?
(Surface tension $=75\times 10^{-3}N/m$ and $g=10m/s^2$.)

A 10 cm long wire is placed horizontally on the surface of the water and is gently pulled up with a force of $2\times {10}^2$N to keep the wire in equilibrium. The surface tension, in ${Nm}^{-1}$ of water is
