*Does air affect what a scale reads? A 60-kg woman with a
density of 980 kg>m3
stands on a bathroom scale. Determine
the reduction of the scale reading due to air.
I need an explanation
The relation between mass and density
density = m/V
V= m/ density
= 60 kg/ 980
=0.0612 m^3
the weight of the air displaced by the air is balanced by the buoyant force
FB = rho air * V g
=1.29 ( 0.0612)(9.8)
=0.774 N

P1. (10 points) A rock is suspended from a scale that reads 20.0 N (in air). A beaker of water (having a density of 1000 kg/m3) is raised up so the rock is totally submerged in the water. The scale now reads 12.5 N. What is the density of the material of rock?
The mass of a block of metal reads as 0.56-kg when weighed in air. Once the block is completely submerged in water the same spring scale reads 0.21-kg. What is the density of this metal? Please report your answer in kg/m3.
A 66 kg woman stands on a very light, rigid board that rests on
a bathroom scale at each end, as shown in figure.What is the reading on each of the scales?On the right scale. Express your answer using two significant
figures.
Please Help!!!!!!

A woman stands on a scale in a moving elevator. Her mass is 57.5 kg, and the combined mass of the elevator and scale is an additional 815 kg. Starting from rest, the elevator accelerates upward. During the acceleration, the hoisting cable applies a force of 9870 N. What does the scale read during the acceleration?
