Answer:
The windowpanes are- transparent.
The color of the panes are due to the wavelengths of light that the glass- allows to pass through
Explanation:
Just answered the question.
Wood frogs have this adaptation where they accumulate urea in their bodies and convert their liver glycogen to glucose to act as cryoprotectants. This prevents the formation of ice crystals in their bodies that could cause damage cells during freezing in winter.
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.
Answer:
If the frequency of the source is increased the current in the circuit will decrease.
Explanation:
The current through the circuit is given as;
![I = \frac{V}{Z}](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7BV%7D%7BZ%7D)
Where;
V is the voltage in the AC circuit
Z is the impedance
![Z = \sqrt{R^2 + X_L^2}](https://tex.z-dn.net/?f=Z%20%3D%20%5Csqrt%7BR%5E2%20%2B%20X_L%5E2%7D)
Where;
R is the resistance
is the inductive reactance
= ωL = 2πfL
where;
L is the inductance
f is the frequency of the source
Finally, the current in the circuit is given as;
![I = \frac{V}{\sqrt{R^2 + (2\pi fL)^2} }](https://tex.z-dn.net/?f=I%20%3D%20%5Cfrac%7BV%7D%7B%5Csqrt%7BR%5E2%20%2B%20%282%5Cpi%20fL%29%5E2%7D%20%7D)
From the equation above, an increase in frequency (f) will cause a decrease in current (I).
Therefore, If the frequency of the source is increased the current in the circuit will decrease.
