  1. Child and Teen BMI Calculator. Body Mass Index (BMI) is a person’s weight in kilograms (or pounds) divided by the square of height in meters (or feet). A high BMI can indicate high body fatness. BMI screens for weight categories that may lead to health problems, but it does not diagnose the body fatness or health of an individual.

  2. Jan 19, 2019 · Definition of lean body mass (lean body weight) Lean body mass is defined as the total weight of the human body minus the weight of all the fat. Essentially lean body mass includes muscle, bone, organs, and water. Simply put, lean body mass is comprised of everything in your body besides body fat. Lean body weight usually ranges from 60 to 90 ...

    In aerospace engineering, mass ratio is a measure of the efficiency of a rocket. It describes how much more massive the vehicle is with propellant than without; that is, the ratio of the rocket's wet mass (vehicle plus contents plus propellant) to its dry mass (vehicle plus contents). A more efficient rocket design requires less propellant to ...

  6. May 13, 2021 · The propellant mass ratio is denoted MR and is equal to the ratio of the full mass to the empty mass: MR = mf / me. MR = 1 + mp / me. The ideal rocket equation indicates that the total change in velocity during a burn depends on the natural log of the mass ratio. So we want the ratio to be a large number to produce a large change in velocity.

  7. Step 1: List the known quantities and plan the problem. Apply the law of multiple proportions to the two compounds. For each compound, find the grams of copper that combine with 1.00 g of chlorine by dividing the mass of copper by the mass of chlorine. Then find the ratio of the masses of copper in the two compounds by dividing the larger value ...
