If the "endocrine system" is on your list, I think it's the best choice
for an answer. If it'd not, then I can't help you, because you won't

Answer: t=4.6*R*L
Explanation: In order to explain this problem we have to take into account the expression for the current in a RL electric circuit, which is given by:
where If is the final current for RL circuit If (emf/R)
Considering the final current is getting when I(t) = 0.99*If we have:
reoganising the terms we have:
e^(-t/R*L)=(1-0.99)
ln(e^(-t/R*L))=ln(0.01)
then t=4.6*R*L
<span>Which statement best describes wavelength?
C. Wavelength is the length of one complete wave cycle.
As demonstrated by the Doppler effect, why does sound increase in pitch as a sound source approaches you?
B. The waves are closer together because the object is moving toward you.
