Q. When multiplying 3.24 by 2.1, what is the correct number of significant figures in the final answer?
A.
4
B.
3
C.
2
D.
1
Solution
In multiplication, the result should have the same number of significant figures as the factor with the least significant figures. 3.24 has 3 significant figures and 2.1 has 2 significant figures, so the answer should have 2 significant figures.
Q. When subtracting 5.678 from 10.0, how should the answer be rounded?
A.
4.32
B.
4.3
C.
4.4
D.
4.00
Solution
In subtraction, the result should be rounded to the least number of decimal places. 10.0 has one decimal place and 5.678 has three, so the answer should be rounded to one decimal place: 4.32 becomes 4.3.
Q. When using a potentiometer to measure an unknown voltage, the balance point is found at 4 m. If the known voltage is 12 V, what is the unknown voltage?
A.
6 V
B.
8 V
C.
12 V
D.
16 V
Solution
Using the formula Vx/Vk = Lx/Lk, we have Vx = Vk * (Lx/Lk). Here, Lx = 4 m, Lk = 10 m, Vk = 12 V, thus Vx = 12 V * (4/10) = 4.8 V.
Q. When using a potentiometer to measure an unknown voltage, what is the condition for balance?
A.
The current through the potentiometer must be maximum
B.
The potential difference across the galvanometer must be zero
C.
The resistance of the potentiometer must be zero
D.
The length of the wire must be equal to the unknown voltage
Solution
The condition for balance in a potentiometer is that the potential difference across the galvanometer must be zero, indicating that the unknown voltage is equal to the voltage across the potentiometer wire.
Correct Answer:
B
— The potential difference across the galvanometer must be zero
Q. When using a potentiometer to measure the emf of a cell, what condition must be satisfied?
A.
The circuit must be closed
B.
The circuit must be open
C.
The cell must be short-circuited
D.
The cell must be connected in series
Solution
The circuit must be open when measuring the emf of a cell with a potentiometer to ensure that no current flows through the cell, allowing for an accurate measurement.
Q. Which agricultural revolution is characterized by the transition from subsistence farming to commercial agriculture in the 18th century?
A.
Neolithic Revolution
B.
Green Revolution
C.
Agricultural Revolution
D.
Industrial Revolution
Solution
The Agricultural Revolution of the 18th century marked the transition from subsistence farming to more commercial agricultural practices, leading to increased productivity.
