Little Red will arrive at her grandmother's house at 5 PM :)

30/10 = 3

2 + 3 = 5

I):final velocity=initial velocity+acceleration due to gravity*time of travel

Therefore,
v=0+9.8*3.1
=30.38 m/s

If by floor you meant water bed then i think there isn't enough info in the question.

Why does the current splits in parallel circuit and why does the voltage remains equal?​
Xelga [282]

<u>Voltage:</u>

It is basically the difference between the charges of the materials on the ends of the Wire

<em>also known as potential difference</em>

It is very similar to the movement of air, it moves from higher density to lower density. in this case, the change in density is the potential difference

So, since voltage is the difference between the charge available on the ends of a wire. Even if the wire splits in parallel circuit, the difference of the charges remains the same

<em>the more the potential difference, the faster electrons will move to the material with lower charge</em>

<u>Current:</u>

Current is the amount of electrons moving through a cross-section of a wire in a period of time

So basically, it is the amount of electrons that move across a given point on a wire in a period of time

If the wire splits, we will have the same amount of electrons moving through as they would if the wire was not split but now, the electrons passing are divided and hence, if we measure the current after the split, we will find that we have a lower current

that's because we have less charge moving through the cross-section of the wire since some of those electrons are moving through a different wire

That's why the current splits in a parallel circuit
