Q. In a system at equilibrium, if the concentration of reactants is increased, what will happen to the equilibrium position?
A.
Shift to the right
B.
Shift to the left
C.
No change
D.
Depends on temperature
Solution
According to Le Chatelier's principle, increasing the concentration of reactants will shift the equilibrium position to the right to favor the formation of products.
Q. In a system of two rotating bodies, if one body has twice the moment of inertia of the other, how does their angular momentum compare if they rotate with the same angular velocity?
A.
The same
B.
Twice as much
C.
Half as much
D.
Four times as much
Solution
Angular momentum L = Iω; if one has twice the moment of inertia, it will have twice the angular momentum at the same angular velocity.
Q. In a system of two rotating disks, if disk A has twice the moment of inertia of disk B and they are both rotating with the same angular velocity, what can be said about their angular momentum?
A.
LA = LB
B.
LA = 2LB
C.
LA = 4LB
D.
LA = 1/2 LB
Solution
Angular momentum L = Iω; since IA = 2IB and ωA = ωB, LA = 2LB.
Q. In a table showing the production output of three factories (A, B, C) over a month, if Factory A produced 500 units, Factory B 700 units, and Factory C 300 units, what is the total production?
A.
1500 units
B.
1400 units
C.
1300 units
D.
1200 units
Solution
The total production is 500 + 700 + 300 = 1500 units.
Q. In a table showing the sales figures for two products (X and Y) across three regions, if Product X sold 500 units in Region 1 and Product Y sold 300 units in the same region, what is the total sales for Region 1?
