Answer 1

If Earth had eight times its present volume, a person's weight at the surface of Earth would decrease by a factor of 8.

Step-by-step explanation:

The weight of a person at the surface of Earth is given by the equation W = mg, where W is the weight, m is the mass, and g is the acceleration due to gravity. If Earth had its present mass but eight times its present volume, the gravitational field strength at the surface would decrease by a factor of 8. Therefore, the weight of a person would decrease by a factor of 8.

The question relates to the calculation of Estimated Energy Requirement (EER) with a given formula for women and involves variables such as age, physical activity level (PA), weight (WT), and height (HI). Additionally, it touches upon concepts of linear regression, calculating weight under different planetary conditions, z-scores for weight in a child development context, and the energy efficiency ratio (EER) in terms of heat transfer and work input. It is important to use the given EER equations and data from tables and studies mentioned to solve the related exercises. For instance, calculating z-scores would involve subtracting the mean from the given weight and dividing by the standard deviation.
