Answer:
120 mA
Explanation:
The relationship between voltage, current and resistance in a circuit is given by Ohm's law

where
I is the current
V is the voltage
R is the resistance
In this problem, we have an initial current of
I = 60 mA
Then the voltage is doubled:
V' = 2 V
while the resistance is kept the same:
R' = R
So the new current is

so, the current has doubled. Since I = 60 mA, the new current is

A. is a neutral substance.
Only neutral substances (like pure water) can have a pH of 7.
A larger diameter wire has lower resistance. A lower resistance wire produces less heat for a given current flowing through it.
