Q. If the density of a substance is measured as 8.0 g/cm³ with an uncertainty of ±0.2 g/cm³, what is the absolute error in the volume calculated from this density?
A.
0.025 cm³
B.
0.1 cm³
C.
0.2 cm³
D.
0.5 cm³
Solution
Volume = mass/density; if mass is constant, the absolute error in volume = (mass * absolute error in density) / (density²).
Q. If the depth of a river increases by 2 m and the width remains constant, how does this affect the volume of water in a section of the river that is 100 m long? (2022)
A.
200 m³
B.
100 m³
C.
300 m³
D.
400 m³
Solution
Volume = Width x Depth x Length. Increase in volume = Width x 2 m x 100 m. Assuming width = 1 m, Volume = 1 m x 2 m x 100 m = 200 m³.
Q. If the depth of a river increases by 2 m and the width remains constant, how does this affect the volume of water if the length of the river is 1000 m? (2019)
A.
2000 m³
B.
1000 m³
C.
4000 m³
D.
3000 m³
Solution
Volume = Length × Width × Depth. If width is constant, Volume increase = 1000 m × Width × 2 m = 2000 m³.
Q. If the diagonal of a square is 10√2 cm, what is the area of the square?
A.
100 cm²
B.
200 cm²
C.
50 cm²
D.
150 cm²
Solution
The diagonal d of a square is related to the side length s by the formula d = s√2. Therefore, s = d/√2 = 10√2/√2 = 10 cm. The area is s² = 10² = 100 cm².
Q. If the diameter of a wire is halved while keeping the length constant, what happens to its tensile strength? (2019)
A.
It doubles
B.
It halves
C.
It quadruples
D.
It remains the same
Solution
Tensile strength is inversely proportional to the cross-sectional area. Halving the diameter reduces the area to a quarter, thus tensile strength quadruples.
Q. If the difference between the compound interest and simple interest on a certain sum of money for 2 years at 10% is $50, what is the principal? (2000)
A.
$1000
B.
$1200
C.
$1500
D.
$2000
Solution
The difference between CI and SI for 2 years is given by P * (r^2)/100^2. Setting this equal to $50 and solving gives P = $1500.
