Answer:
16 N
Explanation:
The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.
We have,
Input force = 8 N
Input arm distance = 6 m
Output arm distance = 3 m
We need to find the resulting output force. So,

So, the resulting output force is 16 N.

Answer :
1. It will shift left ( as heat is added)
2. It will shift right ( as it cooled down)
Explanation :
For an exothermic reaction, heat is a product. Therefore, increasing the temperature will shift the equilibrium to the left, while decreasing the temperature will shift the equilibrium to the right.
