Physics labQuestion $(2)$: $(5$ marks$)$

a$)$ What is the name of the instrument below and what is it's reading:

The Name:

$q,$

The reading:

$(.q,$ mm$)$

b$)$ The mass and the diameter of a given sphere are measured as shown in the table below:

$\backslash$table$[[$Mass $($g$),,$Diameter $(mm),],[43\mathrm{.}25,,31\mathrm{.}20,],[43\mathrm{.}30,,31\mathrm{.}22,],[43\mathrm{.}35,,31\mathrm{.}21,],[,,,]]$

Write the mass and the diameter in the format $(\stackrel{}{x}x).$

$\frac{?}{\text{b}\text{a}\text{r}}(m)x=$

$\frac{?}{\text{b}\text{a}\text{r}}(d)x=$

Calculate the volume of the sphere in $(c{m}^3).$

Calculate the density of the sphere in $(\frac{g}{c}{m}^3).$
