Answer:
c) 22,920 years
Explanation:
The half-life of C-14 is 5730 so in 5730 years , amount of C-14 is reduced to half.
In 5730 x 2 years , the amount of C-14 is reduced to 1/4 .
In 5730 x 3 years , the amount of C-14 is reduced to 1/8 .
In 5730 x 4 years , the amount of C-14 is reduced to 1/16 .
In 22920 years , the amount of C-14 is reduced to 1/16 .
So the answer is 22920 years.
<span>A cyclotron can not accelerate neutrons since a neutron has no charge. Cyclotrons can only accelerate charged particles. </span>
Answer: A theory arises from repeated observation and testing and incorporates facts, laws, predictions, and tested hypotheses that are widely accepted. A hypothesis is a specific, testable prediction about what you expect to happen in your study. Hope this helps :)
Explanation:
Hello! Light waves are an example of electromagnetic waves. I hope this helps!
here we can use energy conservation
like initial kinetic + potential energy is always conserved and it will be same at all points
so we can say
now we can plug in all the given values in it
now divide whole equation by mass "m"
so final speed will be 65.96 m/s
