Explanation:
Using p1p1=p2p2
(75-73.5)x8=(X - 74)X 6
1.5 X 8= 6x-444
12=6x-444 (add 12)
6x=456 (divide by 6)
X= 76cm
Therefore the answer for the barometric height is 76cm
In order to make an electric current flow it is necessary to have a source of the current or source of free electrons and also the circuit should be a close one or complete. When there is a break in a circuit, no current would flow in the whole system.
