Answer:
2023857702.507m
Explanation:

recall from newton's law of gravitation
G=gravitational constant
mshew=50g
melephant=5*10^3kg
rearth=radius of the earth 6400km or 6400000m
mearth= masss of the earth
Gm(shrew)m(earth)/r(earth)^2 = Gm(elephant)m(earth)/r^2
strike out the left hand side and right hand side variables
m(shrew)/r(earth)^2 = m(elephant)/r^2
r^2 = m(elephant).r(earth)^2 / m(shrew) .........make r^2 the subject of the equation
r^2=
r^2=40960000000000
r=2023857702.507m
If coal was our Primary source it would help the world but population would be higher and it can damage animals,people will be able to drive calm without problems ithe world
Firstly, you must identify the pure substance first. Then, from a reliable source obtain its density. Density is calculated through the equation,
density = mass / volume
From this equation, the volume can be calculated.
volume = mass / density
