Chapter 1: Q43P (page 11)

A person on a diet might lose 2.3kgperweek. Express the mass loss rate in milligrams per second, as if the dieter could sense the second-by-second loss.

Short Answer

Expert verified

The mass-loss rate is 3.8m/s.

Step by step solution

01

Given data

The given rate of loss of mass is2.3kg/week.

02

Understanding the unit conversion

Unit conversion is the conversion between different units of measure for the same quantity, usually through multiplier conversion factors.

03

Determination of mass-loss rate in required units

Using the conversion of mass (Kg) in milligram and time (week) into seconds, find the mass-loss rate.

It is known that,

1kg=103gm=106mg

Therefore, the rate of loss in milligrams per week is 2.3脳106mg/week.

The number of seconds per week is,

Numbersecondsperweek=(7daywek)(24hrday)(3600shr)=604,800s/week

So, the rate of loss of mass is,

Masslossrate=2.3脳106mg604800s=3.8mg/s

Thus, the rate of loss of mass is3.8mg/s .
