20oC
30oC
34oC
70oC
Correct answer is A
\(\frac{x - 0}{100 - 0} = \frac{14 - 10}{30 - 10}\)
x = \(\frac{100 \times 4}{20} = 20^oC\)
Mechanical energy can be either
kinetic or electric

50.0N
120.0N
200.0N
240N
Correct answer is B
V.R = \(\frac{1}{sin\theta} = \frac{1}{sin 30} = 2\)
M.A = \(\frac{E \times V.R}{100} = \frac{50 \times 2}{100} = 1\)
Effort = \(\frac{load}{M.A} = \frac{120}{1} = 120N\)
