You need to make a spring scale to measure the mass of objects hung from it. you want each 2.3 cm length along the scale to correspond to a mass difference of 0.10 kg. what should be the value of the spring constant?

42.6 N/m

Explanation:

The spring constant can be found by using Hooke's law:

F = kx

where

F is the force applied

k is the spring constant

x is the stretching/compression of the spring

In this problem, the mass applied is

m = 0.10 kg

so the force applied is the weight of the mass:

The stretching of the spring is

x = 2.3 cm = 0.023 m

So the spring constant is

your answer is c! hope this : )
