A rock on earth has a weight of 135 Newtons. What is its mass?

Explanation:

An object that has a mass of 1 kg weighs about 9.8 N. So if you already know the mass of an object and you want to know its weight in Newtons, you simply multiply the number of kilograms by 9.8 N. Conversely, if you know an object's weight in Newtons, you can divide by 9.8 N, and you'll get that object's mass.

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.

d.7.5cm is your answer
