Answer:
Explanation:
For this exercise let's use hooke's law
F = - k x
where x is the displacement from the equilibrium position.
x = 
if we have several springs in series, the total displacement is the sum of the displacement for each spring, F the external force applied to the springs
x_ {total} = ∑ x_i
we substitute
x_ {total} = ∑ -F / ki
F / k_ {eq} = -F 
1 / k_ {eq} = ∑ 1 / k_i
if all the springs are the same
k_i = k
Let's give it a whirl .....
Two disadvantages Retooling and conversion of machines and equipment in the US would be very expensive
Some expressions in the English language would eventually be quite strange: “A miss is as good as a mile”; “Inching along…”; “Ten gallon hat”; “The whole nine yards” & etc. Advantages everything is based on 10 so its easy to switch units
scientists can share info internationally
If a ball is if a ball is dropped from a 576ft building it would take about 8 seconds for it to hit the ground.
E=Eq,
where F is the electrostatic force (or Coulomb force) exerted on a positive test charge q.
