Why is it important to maintain a constant volume of reactants despite changing the relative amounts of reactants?
answer : the correct option is, (d) 3200 joules
solution : given,
force applied = 1600 n
displacement = 2 m
formula used :
w = work done
f = applied force
d = displacement
now put all the given values in the above formula, we get the work done.
therefore, the amount of work done was, 3200 joules
i would say c. petroleum
a is wrong
b is impractical for "mainly used"
d thats too expensive
