Dolphins and other sea creatures can leap to great heights by swimming straight up and exiting the water at a high speed. A 200 kg dolphin leaps straight up to a height of 7.8 m . When the dolphin reenters the water, drag from the water brings it to a stop in 1.8 m . Assuming that the force of the water on the dolphin stays constant as it slows down.

a. How much time does it take for the dolphin to come to rest?
b. What is the force of the water on the dolphin as it is coming to rest?

Go to the bathroom and vape

The answer would be a) -80of

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
