Una araña con una masa de 0.26g cuelga verticalmente de uno de sus hilos. El hilo tiene una constante de resorte de 7.1N/m. ¿Cuál es el aumento de la longitud del hilo causado por la araña?

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

the answer for apex is the lowest
