Answer:
the volume of liquid decreased due to evaporation from the exposed free surface of water so molecules got evaporated .
evaporation occurs at room temperature.
Hi there!
We can use the rotational equivalent of Newton's Second Law:
![\huge\boxed{\Sigma \tau = I \alpha}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5CSigma%20%5Ctau%20%3D%20I%20%5Calpha%7D)
Στ = Net Torque (Nm)
I = Moment of inertia (kgm²)
α = Angular acceleration (rad/sec²)
We can plug in the given values to solve.
![\Sigma \tau = (4 * 10^{-5})(150) = \boxed{0.006 Nm}](https://tex.z-dn.net/?f=%5CSigma%20%5Ctau%20%3D%20%284%20%2A%2010%5E%7B-5%7D%29%28150%29%20%3D%20%5Cboxed%7B0.006%20Nm%7D)
