Potential difference is difference of potential (between points).
<h2>Hello!</h2>
The answer is: A. 4.5 L
<h2>
Why?</h2>
According to the conversion factor which states that:

It means that we have 3.78 L per each gallon or it's equal to say that we 0.26 gallon per each L.The SI unit for liquid volume is the Liter (L)
Let's make the calculations:

So, we have 4.54 L in 1,2 gallons.
Have a nice day!

Answer:
Torque on the coil will be ZERO
Explanation:
As we know that the magnetic moment of the closed current carrying coil is always along its axis and it is given as

now we know that magnetic field is also along the axis of the coil so here as we know the equation of torque given as

so we have


Answer:
Graph F.
Explanation:
From the question given above, the following information were obtained:
1. The car travelled at a constant speed of 15 m/s for 2 minutes. This implies that the car is already moving and the graph can not be drawn from the origin.
Therefore, graph G is wrong.
2. The car increases its speed from 15 m/s to 25 m/s during the next minute and travels at a constant speed of 25 m/s for 2 more minutes.
This implies that the graph of the motion will project upward.
Therefore, graph H and J are wrong.
From the illustrations above, graph F gives the correct discription for the motion of the car.
