The sample's density with respect to the volume it displaces is equal to: C. 0. 60 g/mL
<u>Given the following data:</u>
To calculate the sample's density:
First of all, we would determine the volume displaced by the sample;

Volume displaced = 3 mL
Density can be defined as mass all over the volume of an object. Thus, density is mass per unit volume of an object.
Mathematically, the density of a substance is given by the formula;

Substituting the given parameters into the formula, we have;

Density = 0.60 g/mL

Below is the solution:
<span>centripetal accel = 1.5*g
ω²r = 1.5*9.8m/s²
ω² * 8m = 14.7 m/s²
ω = 1.36 rad/s * 1rev/2πrads * 60s/min = 12.9 rpm</span>
The proton and the neutron both have <em>1 AMU </em>of mass.
