A2.0-m length of wire is made by welding the end of a 120-cm-long silver wire to the end of an 80-cm long copper wire. each piece of wire is 0.60 mm in diameter. the wire is at room temperature, a potential difference of 9.0 v is maintained between the ends of the 2.0-m composite wire .
a.) what is the current in the copper section? b.) what is the current in the silver section?
b.) what is the magnitude of e in the copper section?
c.) what is the magnitude of e in the silver section?
d.) what is the potential difference between the ends of the silver section of the wire?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
