Answer:
The box will move towards me by the additional force of 60N.
Explanation:
I am pulling the box with a force of 30N and my friend is pushing the box in the same direction with a force of 30N.
Here two forces are exhibited in the same direction that is towards myself as a result the box will move towards me by an additional force of 30N+30N=60N.

Answer:
C₇H₁₁N
Explanation:
To find the chemical formula, first, let's evaluate the given conditions.
1. <u>Is a primary amine</u>:
This means that the amine is connected to a carbon, like NH₂-R
2. <u>The degree of unsaturation of the five-membered carbon ring is equal to three</u>:
One of the degrees of unsaturation is for the five-membered carbon ring, the other two are for pi-bonds. This means that the five-membered carbon ring has 2 pi-bonds inside.
3. <u>There are seven carbon atoms</u>:
Five of these seven carbons are for the carbon ring and the other two are bonded to the primary amine.
From all of the above, we have that the chemical formula is:
C₅H₅-C₂H₄-NH₂ = C₇H₁₁N
