What is the change in internal energy if 30 J of heat are released from a system and the system does 50 J of work on its surroundings?
Use u=Q-W

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
