Correct answer is D
power = mgh
0.25 x 103 = \(\frac {60 \times 10 \times 22}{t}\)
t = 52.8 sec
3 rev s-1
40 rev s-1
360 rev s-1
2400 rev s-1
Correct answer is C
\(\frac{\text {speed of driver}}{\text {speeder driven}}\) = \(\frac{\text {no. of teeth of driver}}{\text {no. of teeth of driven}}\)
\(\frac{120}{V}\) = \(\frac{20}{60}\)
v = 360 rev s-1
2.5m
5.0m
25.0m
50.0m
Correct answer is C
X = ut + \(\frac{1}{2}\)at
= (0 x 10) + (\(\frac{1}{2}\) x 0.5 x 10 x 10)
= 25m
4.50ms-1
11.25ms-1
20.00ms-1
45.00ms-1
Correct answer is C
F = \(\frac{m(v - u)}{T}\)
30 = \(\frac{0.075(v - 0)}{0.05}\)
v = 20ms-1
