Answer:
Explanation:
Let the angle between the first polariser and the second polariser axis is θ.
By using of law of Malus
(a)
Let the intensity of light coming out from the first polariser is I'
.... (1)
Now the angle between the transmission axis of the second and the third polariser is 90 - θ. Let the intensity of light coming out from the third polariser is I''.
By the law of Malus

So,



(b)
Now differentiate with respect to θ.

Answer:
The jug drowns because the density of the jug is more than that of the density of water.
Well, for one thing, it could depend on which fruit is dropped first. You haven't mentioned that.
If they're both dropped at exactly the same time, then the melon at 32m hits the ground first.
It has nothing to do with their masses or weights. It's only a matter of which one has farther to fall. Even if it were a school-bus at 96m instead of a pomegranate, anything dropped from less than 96m would reach the ground in less time than the school-bus.
