B. Body Mass Index (BMI) calculation. (8 points) - Brainly Answer: BMI=kg m2 BMI Explanation: BMI=kg m2: 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 BMI: Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women BMI is a rapid way to discover if you are overweight, obese, underweight or normal See more about BMI below in this page
A 3-m steel bar was cooled from 65ºC to 30ºC. What will be . . . - Brainly Answer: To calculate the final length of the steel bar, we need to use the coefficient of linear thermal expansion of steel and the initial length of the bar The formula to calculate the change in length of a material due to a change in temperature is: ΔL = αLΔT where: ΔL = change in length α = coefficient of linear thermal expansion L = initial length ΔT = change in temperature In this case, we have: α = 11 x 10^-6 ºC (coefficient of linear thermal expansion of steel) L = 3 m
