If you can’t open the lid of a jelly jar what should you do?

If I can't open the lid of a jelly jar, I'd keep trying and if I can't open the lid of a jelly jar after the MANY tries I took, I'd ask for help.

Hit in the center of the top, and it will let some air out, that will make it easier.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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//
