What is the definition of half life

Explanation:

Half life is related to the radioactivity. It is used in nuclear physics.

It is the time in which a radioactive substance becomes half of its initial amount.

For example, if the half life of a radioactive substance is 5000 years, it means after 5000 years it becomes half of its initial value or the activity of that substance becomes half after 5000 years.

It is denoted by

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

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//
