Not the answer but the answer will nit be B. hope yall find the answer
Answer:
90 degrees
Explanation:
In the attached image we can see, the condition where this condition (|A+B|=|A-B|) is true.
vector A is pointing horizontally to the right, vector B (positive), points up vertically.
Now analyzing the subtraction of vectors A and B = A - B, we have that vector A continues to point to the right (positive) and vector B points down (negative). In this way the magnitudes of both operations sum and subtraction of vectors is equal.
But the angle between the two vectors (A and B) will remain the same and will be 90°.
d. Butane
Explanation:
The question is asking about the chain isomerism of the compounds.
a. Methane - have 1 carbon atom and does not have isomers.
c. Propane - have 3 carbon atoms and does not have isomers.
b. Ethane - have 2 carbon atoms and does not have isomers.
d. Butane - have 5 carbon atoms and does have two isomers.
You may find the structure of the isomers in the attached picture.

How you got beneficial answer!!
Explanation:
Given that,
The initial velocity of an arrow is 23.4 m/s
We need to find the time taken by it to reach its maximum height. Let the maximum height is h.
Using third equation of motion to find height first.
At maximum height, v = 0
a = -g
Let t is the time to reach its maximum height. So, it can be calculated using second equation motion as follows :
Hence, it will take 2.35 seconds to reach its maximum height.
