Motion depends on what your reference point is. So a good reference point is a tree or a sign, something that is not moving. So if the zebra is walking towards the tree he/she is getting closer to the tree, He/she is in motion. But if the zebra and the tree never get closer or farther apart the zebra is not in motion. HOPE THIS HELPED!! ;D

<span>Store chemical energy and then let it go as electrical energy when they are connected to a circuit.You can make batteries out of many things,like potatoes</span>
Explanation:
You are given the initial velocity, the displacement, and the acceleration. You're looking for the final velocity. So you use the equation:
v² = v₀² + 2aΔy
When you solve for v, you take the square root. Your calculator will return a positive answer, but there are actually two possible answers: positive and negative.
v = ±√(v₀² + 2aΔy)
You must use the physical context of the problem. If we take up to be the positive direction, then v must be negative, since the projectile is moving down.
Answer:
The distance from the positive plate at which the two pass each other is 0.0023 cm.
Explanation:
We need to find the acceleration of each particle first. Let's use the electric force equation.
<u>For the proton</u>
<u>For the electron</u>
Now we know that the plate separation is 4.26 cm or 0.0426 m. The travel distance of the proton plus the travel distance of the electron is 0.0426 m.
Both of them have an initial speed equal to zero. So we have:
With this time we can find the distance from the positive plate (x(p)).
Therefore, the distance from the positive plate at which the two pass each other is 0.0023 cm.
I hope it helps you!
