Homework Statement
I know that you can't convert between the two because one is the rate at which energy is produced and another is an amount of energy. I need to find out how much energy was used for 417 billion kilowatt hours. This was the amount for a year. Is there a way to get it in...
Right i almost forgot! But would u mind explaining why it is the full electrostatic force? My reasoning for it beeing half is your only working with half of the triangle. Therefore wouldn't the force only be half because your only using half of the triangle?
Thanks alot! And by 28 i mean the angle between the 2 pith balls so it would actually be 14 degrees between the Fg and T. I think i could then use the angle to solve for the hypotenuse/ tension. I would then use Pythagorean's Theorem to solve for the other side of the triangle which is Fe. I...
Homework Statement
I have 2 equally charged pith balls suspended by a string repelling each other at a 28 degree angle. I know that Tension, Gravity, and the electostatic force are all acting. I found tension by creating a force diagram. T= cos14mg. I also found g=mg. I'm having trouble...
Thanks i see what your saying. Just one question about the graph. I'm having trouble deciding what should be on each axis. Would it be a KE vs D or would a mass drop out on each side and you would be left with velocity vs D ?
Homework Statement
My task is to design a lab in which i can solve for the coefficient of friction for a razor scooter( the little medal kids one). I planned on varying velocities and distance to show that the coefficient remained constant. Does anyone see any improvements that could me...
