Answer:
<h2>The potential difference is 60mV</h2>Explanation:
This problem bothers on application of the expression for motion emf which is expressed as
where B= magnetic field in Tesla
l= length of the conductor
v= speed of conductor
Given data
l= 2 meters
v= 6 m/s
B= 5 Tesla
Applying the formula we have
After one half-life, 8 g of radioactive isotope will remain in the sample.
<h3>What is radioactivity?</h3>The act of producing radiation spontaneously is known as radioactivity. This is accomplished by an unstable atomic nucleus that want to give up some energy in order to move to a more stable form.
The following formula is used to compute the number of half lives elapsed:
Hence,8 gram of radioactive isotope remains in the sample after 1 half-life.
