In a figure a ladder 20 ft. long leans against a vertical frictionless wall And makes an angle of 53 degrees with the horizontal which is a rough surface. The ladder is in equilibrium. Its weight is 80 pounds and its center of gravity is in teh center of the ladder. Find teh magnitudes and...

You lost me here, i can't follow your logic. you say that today is today what will be tommorow in another universe? and you also assume that there are infinite amounts of parallel universes, what if there are only 2 universes. and for the exist part, "I Think therefore I am" Descartes Now...

I was riding the subway yesterday on the way back from a concert, and i saw a girl holding a helium balloon and when the train started moving the balloon moved foward with the train, i thought that because of the acceleration and the inertia the balloon would move back, but it actually went...

Light speed...Impossible Faster than light..Probable? With all the talk of speed of light and what not i have to ask. Einstien said that to travel at the speed of light required an infinite amount of energy, correct? Einstien also said that it is impossible to go from a velocity of below the...

When was Newton wrong? Not to challenge you entropy but i have never heard that and i am curious. And the perpetual motion machine, i was told by my physics teacher that it can never happen, due to the fact that no machine can , at this moment in time, have 100% effeciency due to energy...

nah that's great, thanks alot

I was told of sonoilluminessence brieflly in class, i am interested in it, how does it work? and why did scientists want to see if they could create light from sound/ how did the scientists do it? I am also curious if i spelled it right

thanks man, that helps alot

breast cancer

I also need help with this problem, it involves energy and i just can't crack the problem by using what i know, i can't even start it, so here it is: A wooden Block whose intitial speed is 6 m/s starts to slide up an incline plane at 25 degrees above the horizontal. a)if the coeffiecent of...

thanks a million man, that really helps me out

what was that formula again i just need a better theory behind itm that was a little fast

a 3.00 kg block starts from rest @ the top of a 30-degree and slides 2.00 m down in 1.50s. Find (a) the acceleration of the block (b) the coefficient of kinetic friction between it and the incline, (c) the frictional force acting on the block, and (d) the speed of the block after it has slid...
