Explanation:
The given reaction equation will be as follows.
Let is assume that at equilibrium the concentrations of given species are as follows.
M
M
M
Now, first calculate the value of as follows.
=
=
Now, according to the concentration values at the re-established equilibrium the value for will be calculated as follows.
M
Thus, we can conclude that the concentration of in the new equilibrium mixture is
M.
Answer: The correct answer is option(A).
Explanation:
Total forces exerting on the car = F
= Force on car exerting in right direction
= Force on car exerting in left direction
= Force on car exerting in upward direction
= Force on car exerting in downward direction
(negative sign shows the direction)
Since, upward force are equal in magnitude but opposite in direction by which they will balance out each other.so, the net force car will be due to two forces and
(negative shows the direction)
The magnitude (size) and direction of the cumulative force acting on the car will 30 N towards right direction.Hence, correct answer is option(A).
