The answer is </h2><h2>
a. 5g/mL</h2>
Explanation:
Given data
mass m= 45g
volume v= 9mL
we know that density=m/v
substituting our given data we have
What is Density?
The Density of a body can be defined as the ratio of mass to volume,
or
Density, mass of a unit volume of a material substance. The formula for density is ,
where d is density,
M is mass, and
V is volume.
Density is commonly expressed in units of grams per cubic centimetre.

Explanation:
Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:
Hope this helps!
If everything else is held constant ... the substance from which
the conductor is formed, its cross-sectional area, its temperature
everywhere along its length ... then yes, its resistance will be
directly proportional to its length.
