The half-life equation in which <em>n </em>is equal to the number of half-lives that have passed can be altered to solve for <em>n.</em>
<em></em>
<em></em>
Then, the number of half-lives that passed can be multiplied by the length of a half-life to find the total time.
<em>2 * 5700 = </em>11400 yr
The momentum of a neutron p = 586.25 kg m / s.
<u>Explanation:</u>
The product of mass and the velocity gives the momentum of an object and it is a vector quantity. It is denoted by the letter p. The unit of momentum is kilogram meter per second (or) kg m / s.
Given mass m = 1.675 10, velocity v = 3.500
10
Momentum, p = mv
where m represents the mass,
v represents the velocity.
momentum p = (1.675 10)
(3.500
10)
momentum p = 586.25 kg m / s.
