Correct answer is A
Given; VR = 6, e = 75%, MA = ?
e = \(\frac{\text{MA}}{\text{VR}} \times \frac{100}{1}\)
MA =\(\frac{75 \times 6}{10}\)
MA = \(\frac{9}{2}\)
MA = \(\frac{L}{E} = \frac{100}{E}\)
\(\frac{9}{2} = \frac{100}{E}\)
9E = 100
E = \(\frac{200}{9}\)
= 22.2N

10J
103J
104J
105J
Correct answer is D
Ke = mgh
Ke = Pe
\(\frac{1}{2}\)MV2 = mgh
Ke = 1000 x 10 x 10
Ke = 100000J
Ke = 105J
133.2g
66.0g
60.0g
22.0g
Correct answer is B
clockwise movement = anticlockwise movement
w x 10 = 22 x 30
w = \(\frac{22 \times 30}{10}\)
w = 66.0g
