The two main things are speed and velocity. you have to factor in a bunch of smaller things too, but those don't really have much of an effect. And mass inertia is the resistance of any physical object to any change in its state of motion. The velocity of an object will determine the inertia that the object has. Good luck on your assignment and have a great day! :D
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>
