Q9. The function of the cerebellum in the human brain is to control
Avoluntary actions
Bposture and balance
Cbreathing and heartbeat
Dmemory and learning
Correct Answer: B

Q10. X and Y are two events. The probability of X or Y is 0.7 and that of X is 0.4. If X and Y are independent, find the probability of Y.
A0.30
B0.50
C0.57
D1.80
Correct Answer: A
P (X or Y) = P(X) + P(Y), when they are independent as given.
0.7 = 0.4 + P(Y)
P(Y) = 0.7 - 0.4 = 0.30

Q15. A wheel and an axle is used to raise a load whose weight is 800N when an effort of 250N is applied. If the radii of the wheel and axle are 800mm and 200mm respectively, the efficiency of the machine is
A90%
B80%
C85%
D87%
Correct Answer: B
Given information:
Load, L = 800 N
Effort, E = 250 N
Radius of wheel, R = 800 mm = 0.8 m
Radius of axle, r = 200 mm = 0.2 m
Solution:
Step 1: Calculate velocity ratio
For a wheel and axle, velocity ratio VR = R / r = 0.8 / 0.2 = 4
Step 2: Calculate mechanical advantage
Mechanical advantage MA = L / E = 800 / 250 = 3.2
Step 3: Calculate efficiency
Efficiency η = MA / VR × 100% = 3.2 / 4 × 100% = 0.8 × 100% = 80%
