Answer:
<em> 3980.89 ohms</em>
Explanation:
The capacitive reactance is expressed as;
![X_c = \frac{1}{2 \pi fC}](https://tex.z-dn.net/?f=X_c%20%3D%20%5Cfrac%7B1%7D%7B2%20%5Cpi%20fC%7D)
f is the frequency
C is the capacitance of the capacitor
Given
f = 60H
C = C1+C2 (parallel connection)
C = 15μF + 25μF
C = 40μF
C = ![40 * 10^{-6}F](https://tex.z-dn.net/?f=40%20%2A%2010%5E%7B-6%7DF)
Substitute into the formula:
![X_c = \frac{1}{2(3.14)*60*40*10^{-6}}\\X_c = \frac{1}{0.0002512}\\X_c = 3,980.89](https://tex.z-dn.net/?f=X_c%20%3D%20%5Cfrac%7B1%7D%7B2%283.14%29%2A60%2A40%2A10%5E%7B-6%7D%7D%5C%5CX_c%20%3D%20%20%5Cfrac%7B1%7D%7B0.0002512%7D%5C%5CX_c%20%3D%203%2C980.89)
<em>Hence the total capacitive reactance is 3980.89 ohms</em>
Answer:
The after the light changes to more energetic Violet light
Explanation:
This type of thermometer is called a pyrometer, the light from the bulb is facing the light received from the hot object by moving the knob to the right for more current through the filament and the light changes towards more energy, violet. When the intensity from the hot source and the deserter are the same, the radiation is absorbed and the device is black, at this time the temperature is read.
The after the light changes to more energetic Violet light
Answer:A hibernation to lower metabolism in the winter
Explanation:
the others would not be beneficial in the tundra since the tundra is cold adaptations that retain heat would be best
Answer:
Simple cuboidal epithelia
Explanation:
Simple cuboidal epithelia are observed in the lining of the kidney tubules and in the ducts of glands. In simple columnar epithelium, the nucleus of the tall column-like cells tends to be elongated and located in the basal end of the cells.
