The answer is A. 5 n up deals with balanced and unbalanced forces.
Answer:
I = 3.42 A
Explanation:
Ohm's law gives a relationship between the potential difference and the current passing through a conductor. The formula of Ohm's Law is given as follows:
V = IR
where,
V = Voltage
I = Current
R = Resistance
Initially:
V = 14 volts
I = 4 A
R = ?
Therefore,
14 volts = (4 A)R
R = (14 volts)/(4 A)
R = 3.5 Ω
Now, when V becomes 12 volts and R remains constant:
V = IR
12 volts = I(3.5 Ω)
I = (12 volts)/(3.5 Ω)
<u>I = 3.42 A</u>
The answer would be, "Granite".
