Many sailboats are moored at a marina 4.4 km away on the opposite side of a lake. you stare at one of the sailboats because, when you are lying flat at the water's edge, you can just see its deck but none of the side of the sailboat. you then go to that sailboat on the other side of the lake and measure that the deck is 1.5 m above the level of the water.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

The total amount of energy contained in an object
