This is the data sheet for the type of resistor that I'm using: http://selfbuilt.net/datasheets/GM55.pdf. Does light resistance represent the range at which the resistivity will go to when exposed to light? So if it's 30 - 50 k ohms, then 50 k ohms is the highest, and if the dark resistance is 3...

That makes so much sense! Thanks so much for your help!

Thanks so much for your help! Yeah the person who told us to do this wasn't very descriptive... and my friend got pretty linear values like 12 ohms one night then 10, then 7.2, or something like that. What kind of response do photoresistors even give? I guess I'll keep all of my values in ohms.

Oh, right, It's the meade 10" LX200-ACF has 10” diameter f/10 ACF optics (focal length 2500mm) if that helps.

Thanks for the help! The light resistance of the particular model of my photoresistor that I'm using is (10 Lux): 30-50 Kohm. The lux value of a full moon on a clear night is 0.27–1.0 lux. How do lux, lumens, and ohms all relate? How would I convert ohms to lux? Also, is the light resistance of...

I'm using a multimeter to measure the light intensity perceived by a photoresistor in ohms. Would the standard brightness the apparent magnitude of the moon? Because I don't know how I would convert that into a standard when I'm measuring the brightness in ohms. Also, yes they're all typos. I...

So, I recently joined a stargazing club, and for our summer activity, we're supposed to use a telescope, a photoresistor, and a multimeter to measure the luminosity of the moon. I know that luminosity can be calculated with the equation, L = σ AT 4, and that brightness can be measured with the...

well not necessarily equals but I'm just supposed to explore gravitational potential energy in relation to the amplitude

Thanks so much for your help! I figured it out that it should be gravitational potential energy = F= kx for elastic force.

Also, the line of best fit was only put there because it fit the best

Right that all makes sense. Yeah I did learn about kinetic energy, but I forgot to include that with the 0.5kg mass (which is constant). And I should have included the acceleration due to gravity. I didn't think that the rubber bands necessarily counted as springs. Which equation would I even...

It's an exponential curve, adjusted to the amplitude averages. I'm supposed to say something like, The purpose of this experiment is to investigate how the period T of a pendulum depends on its length L. Period will be measured is seconds and the length in cm (this is just an example given by...

Thanks :) Constant: The mass of the object being dropped. IV: Height at which mass is dropped. DV: Amplitude of the trampoline. More specifically, the “amplitude” discussed in the experiment, refers to the farthest length reached by the trampoline, as it dips from the landing of the mass.

Homework Statement So I have to write a report based on an experiment that I have conducted. I know that my report is connected with Simple Harmonic motion and Elastic force, but I do not know how to describe it in a more efficient/scientific way. Essentially, I am dropping a weight (constant)...
