Q. A circular loop of wire is placed in a uniform magnetic field. What happens to the induced EMF if the magnetic field strength is doubled?
A.
Induced EMF is halved
B.
Induced EMF remains the same
C.
Induced EMF is doubled
D.
Induced EMF is quadrupled
Solution
According to Faraday's law of electromagnetic induction, the induced EMF is directly proportional to the rate of change of magnetic flux. If the magnetic field strength is doubled, the induced EMF will also double.
Q. A circular loop of wire is placed in a uniform magnetic field. What happens to the induced EMF if the area of the loop is increased?
A.
Increases
B.
Decreases
C.
Remains the same
D.
Depends on the magnetic field strength
Solution
According to Faraday's law of electromagnetic induction, the induced EMF is proportional to the rate of change of magnetic flux. Increasing the area increases the flux, thus increasing the induced EMF.
Q. A city has a population of 1 million people and each person contributes 4 tons of CO2 annually. What is the total CO2 contribution of the city in a year?
Q. A city plans to reduce its carbon emissions by 20% over the next 5 years. If the current emissions are 5000 tons, what will be the target emissions after 5 years?
Q. A city plans to reduce its water consumption by 15% from its current usage of 2 million liters per day. What will be the new daily water consumption?
A.
1.7 million liters
B.
1.8 million liters
C.
1.9 million liters
D.
2 million liters
Solution
New consumption = Current usage - (15% of Current usage) = 2,000,000 - (0.15 * 2,000,000) = 2,000,000 - 300,000 = 1,700,000 liters.
Q. A civil servant has to complete a project in 120 days. If they have already spent 30 days, what percentage of the time is left to complete the project?
A.
75%
B.
70%
C.
80%
D.
60%
Solution
Time left = Total time - Time spent = 120 - 30 = 90 days. Percentage left = (90/120) x 100 = 75%.
Q. A civil servant is required to submit reports every month. If they have submitted reports for 8 months, what fraction of the year have they completed?
Q. A class has 10 boys and 15 girls. If the average height of boys is 150 cm and that of girls is 145 cm, what is the average height of the class?
A.
147 cm
B.
148 cm
C.
149 cm
D.
150 cm
Solution
Total height of boys = 10 * 150 = 1500 cm. Total height of girls = 15 * 145 = 2175 cm. Total height = 1500 + 2175 = 3675 cm. Average height = 3675 / 25 = 147 cm.
Q. A class has 10 students with an average height of 150 cm. If 5 new students with an average height of 160 cm join, what is the new average height of the class?
A.
154
B.
155
C.
156
D.
157
Solution
Total height of 10 students = 10 * 150 = 1500 cm. Total height of 5 new students = 5 * 160 = 800 cm. New total height = 1500 + 800 = 2300 cm. New average = 2300 / 15 = 153.33 cm.
Q. A class has 30 students with an average score of 75. If 5 new students join with an average score of 80, what is the new average? (2023)
A.
76
B.
77
C.
78
D.
79
Solution
Total score of 30 students = 30 * 75 = 2250. Total score of 5 new students = 5 * 80 = 400. New total = 2250 + 400 = 2650. New average = 2650 / 35 = 76.43.
