A parallel circuit contains four branches. One branch has a current flow

of 0.8 A, another has a current flow of 1.2 A, the third has a current

flow of 0.25 A, and the fourth has a current flow of 1.5 A. What is the

total current flow in the circuit?

Suppose you measure the mass of a banana before it rots. You measure the mass again days later after the banana has turned black and find that the mass is less. Use the law of conservation of mass to conclude what happened to the mass of the banana.

At one time in the Earth's history, many people thought the world was flat. Which best explains why the model of the Earth is now round? Models are limited by the science-the more that was discovered, the better the model could be made.
