Solve electrical network problems

Require a logic circuit designing for the attached solution, as much help as possible please as i am lost. The problem does not specify, what valves are a hazardous system, it is a closed system that serves no purpose as far as i can see. I have not studied any thermofluid systems as yet, it seems too much of a jump in kno

Magnetic Balance: Force on a current carrying conductor

The circuit shown below is used to make a magnetic balance to weigh objects. The mass m to be measured is hung from the center of the bar that is in a uniform magnetic field of 1.50 T, directed towards the plane of the figure. The horizontal bar is 60 cm long. It is connected to the battery by thin vertical wires that can suppor

Network flow

Hi Consider any graph G with edge capacities, a source s, and a sink t. Suppose the maximum flow from s to t is greater than 0, so there is a path from s to t. Then there always exists an edge so that increasing the capacity on the edge increases the maximum flow from s to t. Is Answer True or False Thanks
