Answer:
The tension force transmitted through the chains
Step-by-step explanation:
The gravitational force can only pull the block downward, so the first two options are incorrect. Normal force is present only when an object is on a surface, so the last option is also incorrect.
Tension is a force exerted by a string or chain, so the third option is correct.

Answer:
The value of x in terms of a, b ans c is ![x=\frac{ac-ab}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bac-ab%7D%7B2%7D)
Step-by-step explanation:
We have given the expression ![\frac{2x}{a}+b=c](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7Ba%7D%2Bb%3Dc)
We have to find the value of x in terms of a, b and c
So ![\frac{2x}{a}+b=c](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7Ba%7D%2Bb%3Dc)
![\frac{2x}{a}=c-b](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7Ba%7D%3Dc-b)
![2x=a(c-b)](https://tex.z-dn.net/?f=2x%3Da%28c-b%29)
![2x=ac-ab](https://tex.z-dn.net/?f=2x%3Dac-ab)
![x=\frac{ac-ab}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bac-ab%7D%7B2%7D)
So the value of x in terms a ,b and c is ![x=\frac{ac-ab}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bac-ab%7D%7B2%7D)
Answer:
48 Units
Step-by-step explanation:
Use the Pythagorean theorem to make two right triangles.
Ex= Base is cut in half to make two 9 unit bases
Then count the units from the half point.
Ex= 12 units long
Then use Pythagorean theorem to find one side of the 9-12 right triangle
Ex= 9^2+12^2=c^2
After finding that c=15 units, add all the sides back together
Ex= 18+15+15=48
