That's right, the correct answer is
<span>A) The isotopes have a long half-life and only remain radioactive for a long time period
The half life of an isotope is the time it takes for the amount of the sample to reduce to half of its initial value. If an isotope has a long half-life, it means it takes a long time to reduce down to a significant level, so it will remain radioactive for a long time period.</span>
Answer:
The rate of current change in the circuit is
Explanation:
From the question we are told that
The capacitor has a value
The inductor has a value
The capacitors voltage is at t = 0s
The new capacitor voltage is
Generally when the switch is closed the potential across the inductor is equal to the potential across the capacitor
So for the inductor
rate of current change is given as
Where is the voltage across the inductor.
Substituting value
The correct answer for this question is this one: C) 2.5s. T<span>he period and frequency of a water wave if 4.0 complete waves pass a fixed point in 10 seconds is that 2.5 s
</span>
Here are the following choices:
<span>A) 0.25s
B) 0.40s
C) 2.5s
D) 4.0s</span>
