Three blocks in contact with each other are pushed across a rough horizontal surface by a
73 N force as shown.
The acceleration of gravity is 9.8 m/s2.

If the coefficient of kinetic energy between each of the blocks and the surface is 0.16 find the magnitude of the force exerted on the 7.2kg block by the 6.6 kg block
Answer in units of N

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

The answer is -6hope this
