(b) A person standing in a lift holds a spring balance with a
load of 5 kg suspended from
it. What would be the reading
of the balance when the lift is
descending with an acceleration
of 3.8ms??

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

the independent variable, or the one that is intentionally manipulated is the speed.

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

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
