a fish tank is a cuboid,100cm by 60cm by 40cm. it is partly filled with water, so that when it is resting on a 60cm edge, the water level reaches the top edge and the midpoint of the base, as shown. what will the height of the water be when the tank is resting on its base(100cm by 60cm face)?

Wooden , walls ,doors ,support

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current

Iwould say earthquakes.

It is 5 hope this you out
