please explane it please how come please explain in audio also​

Answer 1

Answer :

• Unit of surface tension : Energy per unit area.
• Unit of velocity : meter per second.
• Unit of time : second.

Surface tension : E/area = E/m².

Units of velocity × time = m/s×s = m.

Surface tension : E/(velocity × time)²

= E V-² T-².

Option B is the answer.
