Consider the electrical circuit and calculate all the currents in the circuit

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

they should be similar or the same

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
