Electric current enters the battery through the negative terminal, at a high potential than when it exits the battery.
<h3>What is Potential difference?</h3>
This is the amount of work needed to move a unit charge from a reference point to a specific point against an electric field.
In a battery, electric current moves from negative to the positive terminal with the positive terminal having a higher potential which is the point where it leaves the battery.

Balance and beaker of water. The balance will measure mass and the beaker will measure the volume when you take the initial volume without the key subtracting that value from the value with the key in the beaker
Recall the formula,
∆<em>θ</em> = <em>ω</em>₀ <em>t</em> + 1/2 <em>α</em> <em>t</em> ²
where ∆<em>θ</em> = angular displacement, <em>ω</em>₀ = initial angular speed (which is zero because the disk starts at rest), <em>α</em> = angular acceleration, and <em>t</em> = time. Solve for the acceleration with the given information:
50 rad = 1/2 <em>α</em> (5 s)²
<em>α</em> = (100 rad) / (25 s²)
<em>α</em> = 4 rad/s²
Now find the angular speed <em>ω </em>after 3 s using the formula,
<em>ω</em> = <em>ω</em>₀ + <em>α</em> <em>t</em>
<em>ω</em> = (4 rad/s²) (3 s)
<em>ω</em> = 12 rad/s
Answer: The recently discovered Eris orbits the Sun every 557 years. ... 67.69 AU; since the average distance for Pluto from the Sun is 39.3 AU then the distance is nearly twice.
Explanation:
