Solution
Let a cell of emf E be connected across the entire length L of a potentiometer wire . Now , if the balance point is obtained at a length l during measurement of an unknown voltage
.
The balance point is not on the potentiometer wire - this statement means that
. In that case ,
l > L
V > E
The type of pollution when small particles of soil are suspended in the water is called Suspended Matter Pollution. <span>This type of pollution happens when soil enter the water and do not mix in with the water molecules.</span>
To form an ion and bond with hydrogen, the oxygen atom gains electrons. Electrons are negative, therefore the oxygen within the water molecule will be negative.
I'm pretty sure the answer to this question is "newton's first law of motion" or d. Hope this helps. :)
