Answer:
Body Mass Index is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

Answer:
The force exerted on the cardboard by the light is
Explanation:
It is given that,
Area of the cardboard,
Intensity of absorbance,
Radiation pressure in case of absorption is given by :
...........(1)
c is the speed of light
The relation between force and pressure is given by :
.......(2)
From equation (1) and (2):
So, the force exerted on the cardboard by the light is . Hence, this is the required solution.
