Answer:
Increase the force applied to the object.
Explanation:
The work done by an object is given by :
.........(1)
Where
F is the amount of force applied
d is the displacement caused due to the force
From equation (1) it is clear that the work done by an object is directly proportional to the applied force. With the increase in force the amount of work done increases.
So, the correct option is (d) "increase the force applied to the object".

Answer:
2KI + Cl₂ → 2KCl + I₂
Explanation:
The reaction equation is given as:
KI + Cl₂ → KCl + I₂
The problem at hand is to balance this chemical reaction. To solve this problem we use a mathematical approach;
aKI + bCl₂ → cKCl + dI₂
Conserving K : a = c
I : a = 2d
Cl : 2b = c
Now let a = 1, c = 1 , d = , b =
, ;
Multiply through by 2;
a = 2, b = 1 , c = 2, d = 1
2KI + Cl₂ → 2KCl + I₂
