The recoil of a 100gram cannon creates a momentum of -200g*m/s. What was the velocity of the cannon? Please help!!
Is it:
A:2m/s
B:-2m/s
C:5m/s
D:0m/s

P. S.If you answer it with no answer then i will REPORT you and make sure you don’t get points just saying!!!BTW IF I GET IT WRONG THAT MEANS U JUST WANTED THE POINTS AND YOU JUST GUESSED SO I WILL REPORT U TOO

the answer to your question is:

c. complementary base-pairing

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

satellites are frequently used to make observations of the orbit on earth

that is wrong, its not thymus.
