Q. A force of 10 N is applied to move an object 5 m in the direction of the force. What is the work done on the object?
A.
10 J
B.
20 J
C.
50 J
D.
5 J
Solution
Work done (W) = Force (F) × Distance (d) × cos(θ). Here, θ = 0° (force and displacement are in the same direction). W = 10 N × 5 m × cos(0°) = 10 N × 5 m = 50 J.
Q. A gas expands isothermally at 300 K from a volume of 1 m³ to 2 m³. If the pressure of the gas is 100 kPa, what is the work done by the gas during expansion? (2019)
Q. A global conference has 4 sessions, each lasting 2 hours. If there are breaks of 30 minutes between each session, what is the total duration of the conference?
Q. A government scheme allocates ₹2,00,000 for 5 different initiatives. If one initiative receives ₹50,000, what fraction of the total budget does it represent?
Q. A group of students has an average age of 20 years. If a new student aged 22 joins the group, what will be the new average age if there were originally 15 students?
A.
20.5
B.
20.6
C.
20.7
D.
20.8
Solution
The total age of the original group is 20 * 15 = 300. Adding the new student gives 300 + 22 = 322. The new average age is 322 / 16 = 20.125, which rounds to 20.6.
Q. A group of students has an average height of 150 cm. If one student leaves the group and the average height becomes 148 cm, what is the height of the student who left?
A.
152 cm
B.
154 cm
C.
156 cm
D.
158 cm
Solution
Let the number of students be n. Total height = 150n. After one leaves, total height = 148(n - 1). Setting the equations gives 150n - 148(n - 1) = height of student.
Q. A group of students has an average height of 160 cm. If one student with a height of 170 cm leaves, what will be the new average height if the group size was 10?
A.
158 cm
B.
159 cm
C.
160 cm
D.
161 cm
Solution
Total height = 160 * 10 = 1600 cm. New total = 1600 - 170 = 1430 cm. New average = 1430 / 9 = 158.89 cm, approximately 159 cm.
