wat do u mean by "time remains constant"...i think u r gettin confused between velocity for K.E with temperature for heat energy...the temperature increases linearly with the increase with addition of energy until the oject phase tranformation stage occurs...at this point the temperature ceases...
i think for 14..it will be workable only by assuming the 3rd particle is a neutrally charged one and by trying to approximate the force experienced by this rticle at varous location such that the net force experienced by this particle is 0...
its pretty simple for the second one too where in case u were jus given the graphs...
g(x+3) means notin but shifting the graph by 3 units to the left...if u could redraw the graph then...just draw it and look for the value at one...or the more simpler approach would be to jus look for the...
to add to this discusion could be the fact that energy is a relative quantity...yes...the energy possed by a system is relative to the observer...on close thought this idea will make itself pretty clear...wit this idea in mind...jus hypothetically thinking...can we define as the measure of...
energy...something that seems to squeeze everyone's mind...for to tell all the truth...man doesn't know too much abt out energy...we have defined energy as "energy is the ability to do work", this would be Force dotted wit distance. such that we get change in energy and if you notice its not...
