Voltage - V = IR : v= voltage i= current r= resistance
Most likely, C. the Moon does not have a liquid core (this is what would create a magnetic field) is correct.
I hope this enough to help you!
In physical science, tension can be described as the motion that applies a pulling force that is transmitted axially through cables, chains, or string. On the other hand, compression is the application of balanced inward forces while extension is the application of balanced outward forces in the same axis through the object.
