A2.0-ohm resistor is connected in a series with a 20.0 -v battery and a three-branch parallel network with branches whose resistance are 8.0 ohms each. ignoring the battery’s internal resistance, what is the current in the batter? show your work.

Explanation:

Resolving the parallel resistor branches

The equivalent resistor is now in series with the 2.0 Ohm resistor

so, by using Ohm's Law

the answer is to check all of them! they all apply well at least i think so!

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2
