Modern fireplaces use a CATALYTIC COMBUSTOR to burn exhaust gases.
A catalytic combustor is an attachment which allows exhaust gases to be chemically broken down to release more energy. This is how it is applicable to modern fireplaces.

Answer:
500 N
Explanation:
Given that,
The upward force is 800 N and the downward forces are 400 N, 500 N, 400 N.
At equilibrium, the upward forces will become equal to the downward forces. Let the reading in the right hand scale.
x + 800 = 400 + 500 + 400
x + 800 = 1300
x = 1300 - 800
= 500 N
So, the reading in the right hand scale is 500 N.
