i cant find answer sorry :((( wish you best of luck <333
Answer:
Explanation:
Sun's dynamo means the process that produce Sun's magnetic field.
The mechanism inside a Sun acts like a generator that produces electric current and magnetic field.
Magnetic field with in the Sun are extended out and around. Magnetic field of lines get twisted due to rotation of Sun.
The material that flows inside the Sun plays an important role in Sun's dynamo. At surface the flow rate is about 20 m/s but as it moves towards equator, it becomes way too slow taking about 11 years of time.
Due to the this magnetic field, several sun spots are formed on the surface.
The number of sunspots keep on changing from minimum to maximum number resulting into change in the magnetic pole. In each cycle polarity get reversed hence the overall magnetic cycle has an interval of 22 years.
It represents the depolarization of the atria.
<u>Explanation:</u>
The P wave speaks to the depolarization of the left and right chamber and furthermore relates to atrial compression. Carefully, the atria contract a brief moment after the P wave starts. Since it is so little, atrial repolarization is typically not unmistakable on ECG.
In an ordinary ECG, there's three particular waves. The primary wave is the P wave, which speaks to the depolarization of the atria. This happens directly before the atria agreement and drive blood into the ventricles. The following wave is known as the QRS wave.
