Thanks! I got it now. I will try to find an average of k's with Hooke's Law. Anyways, can you please explain more about pre-tension? What happens when the spring becomes more linear?
That's what I did; I calculated the change in length from the previous entry. Do you mean that in order to find the spring constant, I have to calculate "x" as overall change in length?
Hi everyone(:
I was reading the other day and I read that the photons don't have the mass. If a light is a flow of photons, how can a light carry an energy or momentum?
I have learned that if the matter was to carry the energy or have momentum, it needs a mass. How can this happen for light...
Homework Statement
The experiment the class did was about spring constant and Hooke's Law. The spring was set vertically and we were to hang the pendulums at the end of the spring and measure the extended length to figure out the spring constant.
and I'm trying to find out why the data...
