Explanation:</h2>
According to Hooke's law, the spring constant (k) of an elastic material is the ratio of the force (F) applied to the material to the extension (x) of the material caused by this force. i.e
k = F / x --------------(i)
From the question, the elastic material (spring) of 25 coils has a spring constant of 350N/m. This means that for every 350N force applied to the spring, the spring extends by 1m.
Now if the spring is cut into five equal parts each with five coils, imagine they are attached together such that the same force of 350N is applied to still cause a total extension of 1m. Each spring contributes 1/5 of this extension.
Therefore, the extension caused by each spring is 1/5 of 1m = 0.2m
Since the same force of 350N is applied, substitute F = 350N and x = 0.2m into equation (i) as follows;
k = 350 / 0.2
k = 1750N/m
Therefore, the spring constant of each of the 5-coil spring is 1750N/m
Ice, which is the solid state of water, the liquid
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
