A body when dropped into a jar ,containing kerosene and glycerine ,sinks below the kerosene level to float in glycerine as infig .What can we say about the densities of kerosene ,glycerine and the body

we can say that that in an increasing order, the body is less dense than the glycerine, and the glycerine is less dense than the kerosene.

Explanation:

If the body sinks below the kerosene level to float in glycerine, then it means that the kerosene is denser than glycerine. This is because bodies will float higher in a denser fluid that a less denser fluid. Also, since the body floats in kerosene and glycerine, then the body is less dense than the kerosene and the glycerine. Finally, we can say that that in an increasing order that the body is less dense than the glycerine, and the glycerine is less dense than the kerosene

the answer is b ) square root of 5

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
