An object with more mass has more kinetic energy than an object with less mass, if both objects are moving at the same speed. <em>(c)</em>
hope it helps:)
Explanation:
A galvanometer is converted into an ammeter by connecting a low resistance in parallel with the galvanometer. This low resistance is called shunt resistance S. The scale is now calibrated in ampere and the range of ammeter depends on the values of the shunt resistance.

You have two possible ways to connect the springs: in parallel or in series.
The equivalent stiffness of three springs in parallel is given by:
k_eq = k₁ + k₂ + k₃
In order to keep this number the smallest possible, you need to take the three springs with smaller k:
k_eq_min = 3.5 + 6 + 8.5 = 18 N/m
The equivalent stiffness of three springs in series is given by:
1 / k_eq = 1 / <span>k₁ + 1 / k₂ + 1 / k₃
In order to get the smallest k_eq possible, 1 / k_eq must be the biggest possible, therefore you need to take again the three springs with smaller k:
k_eq = 1 / (</span>1 / <span>k₁ + 1 / k₂ + 1 / k₃)
= 1 / (1 / 3.5 + 1 / 6 + 1 / 8.5)
= 1.754 N/m
Therefore, in order to get the smallest equivalent stiffness, you need to connect the first three springs in series (one after the other).</span>
