How do you write Einstein's equation that explains the energy from nuclear reactions. Use the caret symbol to show an exponent

e=mc^2
E=mc^2

Which quantity in the equation will most likely be the largest
The half life of cobalt 60 is 5.3 years After years 14 of the original amount of cobalt 60 will remain

A substance is the time required for half the atoms in a sample of a radioactive isotope to decay

The time it takes for half the sample to decay is called the half-life.

The time it takes for half the sample to decay is called the half-life.

The time it takes for half the sample to decay is called the half-life.

The time it takes for half the sample to decay is called the half-life.

In the following decay equation 90 39 y is the

daughter element

What affects the half life

The type of isotope

What can you conclude about a particle labeled 0 -1 e
Factor 2p plus 11p plus 5

2p + 11p + 5 = 13p + 5 which does not factor.

If the expression had been 2p2 + 11p + 5 then this can be factored,

2p2 + 11p + 5 = (2p + 1)(p + 5)
