Body Mass Index (BMI) is calculated using a person’s height and weight to determine their body fat relative to their body structure.
The formula for BMI is:
\(BMI = \frac{Weight (kg)} {Height (m)^2}\)
It is a simple tool to classify individuals into categories like underweight, normal weight, over-weight, or obese.
- Option (a): Only height is insufficient for BMI.
- Option (b): Weight alone cannot determine BMI.
- Option (c): Lean tissue is not directly measured by BMI.
Thus, BMI depends on both height and weight.
Draw the pattern of the magnetic field lines for the two parallel straight conductors carrying current of same magnitude 'I' in opposite directions as shown. Show the direction of magnetic field at a point O which is equidistant from the two conductors. (Consider that the conductors are inserted normal to the plane of a rectangular cardboard.)
