If i have 610J of work done on the system and 76J of internal energy. how much heat much heat was removed or added system undergoes an internal energy of 610J and have added 0.71kJ of heat. does the system do work or have work done on it.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
