D, I believe would be the first minus the second vector.
To solve this I named the first vector as A and the second as B.
So... vector A - B = resultant
or A + (-B)
A negative indicates a direction of a vector so if we flip the direction the other way we have the first vector (A) pointing vertically upwards and then vector B pointing to the west.
Now we have to use the head to tail method, meaning that the head of the first vector has to connect with the tail of the other vector added.
So we should have something like this
(-B) < - - - - ^
|
| (A)
|
To add these two vectors, technically A - B, draw a line from the tail of A to the head of -B which would look like image D.
Hope this helped!
What are the answer choices, if there are any?
A mechanical wave<span> requires an initial </span>energy<span> input. Once this initial </span>energy<span> is added, the </span>wave<span> travels through the medium until all its </span>energy is transferred<span>. In contrast, electromagnetic </span>waves<span> require no medium, but can still travel through one</span>
Answer:
A is false
Explanation:
A is false.
● activation energy affects the rate of a reaction and catalyst affects the rate of reaction too
ΔG (change in free energy) tells if a reaction is spontaneous or not
