Answer:
Distance from the moon= dm= 384,403km
A quarter diameter= dq= 2.3 cm= 0.000023km
No of quarters= 16,713,173, 913
To convert cm into km divide cm by 100 and then by 1000
as
1m= 100cm
1km= 1000m
Therefore
2.3/100= 0.023 m
And
0.023/1000= 0.000023 km
Dividing the distance from the moon by the diameter of the quarter laid end to end would give the number of the quarters needed.
No. of quarters= Distance from the moon/ Diameter of the quarter
= 384,403km/0.000023 km
= 16,713,173,913.043
Rounding 16,713,173,913.043 gives 16,713,173,913 quarters

Answer:
2.29g/cm3.
Explanation:
The following data were obtained from the question.
Mass of the oil = 172g
Volume of oil = 75cm3
Density =..?
Density of a substance is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:
Density = Mass /volume
With the above formula, we can calculate the density of the oil as shown below:
Density = Mass /volume
Density = 172g/75cm3
Density = 2.29g/cm3.
Therefore, the density of the oil is 2.29g/cm3.

Answer:
Momentum is define as the product of the mass and velocity of a body. It is measured in Kgm/s.
Explanation:
Momentum is the product of mass and velocity of an object. When an object or a body of mass 'm' is moving with velocity 'v', then its momentum can be determined as;
momentum (P) = mass × velocity
i.e P = m × v
= mv
It is measured in Kgm/s.
The change in momentum of a body is referred to as its impulse (Ft).
ΔP = m(v - u) = Ft
Where: P is the momentum of the object, m is its mass, v is its final velocity, u is the initial velocity, F is the force and t is the time in which the force acts.
