Q1. Total path 132 m around a circle of radius 7 m (pi=22/7). How many revolutions is that?
- A.3
- B.18.857
- C.6
- D.0.333
Answer: A. 3
Q2. Total path 264 m around a circle of radius 7 m (pi=22/7). How many revolutions is that?
- A.6
- B.37.714
- C.12
- D.0.167
Answer: A. 6
We are told that 264 m, 7 m (physics, chapter 'Describing Motion Around Us'). The unknown we need is How many revolutions is that?. The principle that connects these is - v = u + a*t, F = m*a, PE = m*g*h, n = m/M. The arithmetic is: hence the required answer = 6. The stem provides numerical data: 264, 7, 22, 7. That lands on option A) 6. As for the others, option B) '37.714' doesn't hold - Wrong: a step was skipped or a unit not converted; option C) '12' fails since Wrong: this uses an incorrect intermediate result.
Q3. Total path 176 m around a circle of radius 14 m (pi=22/7). How many revolutions is that?
- A.2
- B.12.571
- C.4
- D.0.5
Answer: A. 2
