Answer:
B
Explanation:
just answered that question
Elastic collision is when kinetic energy before = kinetic energy after
Ek= 1/2mv^2
total before
Ek=1/2(2)(2.2^2) = 4.84 J
total after
Ek= 1/2(2+4)(v^2) = 3v^2
Before = after
4.84=3v^2 | divide by 3
121/75 = v^2 | square root both sides
v=1.27 m/s
Answer:
Ok
Explanation:
Matter has to do with material substance that constitutes the observable universe. Element has to do with an object you are using.
It will be -1 because in valence shell there will be 7 electrons so it will take 1 from other atom to complete its outer shell
