Answer:
Extension, e = 0.0000359 meters
Explanation:
Given the following data;
Mass = 0.26 g
Spring constant = 7.1 N/m
To find the extension of the thread;
Conversion:
1000 grams = 1 kg
0.26 grams = 0.26/1000 = 0.00026 kg
First of all, we would determine the force acting on the spider;
Force = mass * acceleration due to gravity
Force = 0.00026 * 9.8
Force = 0.00255 N
Next, we would determine the extension;
Force = spring constant * extension
Substituting into the equation, we have
0.00255 = 7.1 * extension
Extension, e = 0.00255/7.1
Extension, e = 0.0000359 meters
