The water at Niagara Falls drops through a height of 55.0 m. If the water’s loss of gravitational potential energy shows up as a
n increase in temperature of the water, what is the temperature difference between the water at the top of the falls and the water at the bottom? For this problem, if you need any of these values, use g = 10 m/s^2, take the specific heat of water to be 4000 J/(kg °C), and the latent heat of vaporization of water to be 2 × 10^6 J/kg.__________.
Due to the symmetric location of the +2μC charges the forces the excert over the +5μC charge will cancel each other resulting in a net force with a magnitude of zero.However in this case it would be an unstable equilibrium, very vulnerable to a kind of bucking. If the central charge is not perfectly centered on the vertical axis the forces will have components in that axis that will add together instead of canceling each other.
Well, if I understand correctly, I think it'd be 60, because 60+60= 120, but I may be wrong. It's not my best subject, but why not try to help even though I suck lol.
