Question

A 0.1 g spider is suspended from a thread. What is the tension in the thread?

Answer 1

Tension `= (1xx10^-4)(9.8) = 9.8xx10^-4N`

Explanation:

Vertical tension of an object (or spider) from a surface (thread) is calculated by multiplying the mass of the spider by Earth's gravitational acceleration constant, g, of `9.8m/s^2`

We convert any mass into kilograms, 1000 grams are in 1 kilogram so we divide the 0.1 gram by 1000.

so if there is only one object involved then the equation is `mass(g)` or `0.0001kgxx9.8m/s^2`
