<h3><u>Answer;</u></h3>

Sunspots

<h3><u>Explanation;</u></h3>
  • Sunspots are areas on the surface of the sun that occurs in pairs since each is one side of a loop of the sun's magnetic field which reaches the surface of the sun.
  • <u>Sunspots are cooler and darker than the rest of the Sun's surface and are marked by intense magnetic activity.</u>
  • Sunspot are created by the strong, dense magnetic fields that are generated by circulating plasma which become entangled and surge through the photosphere.

solmaris [256]

Answer:

90 ohms

Explanation:

1/r = 1/180 + 1/180

1/r= 2/180

Two vectors A and B are at right angles to each other. The magnitude of A is 3.00. What should be the length of B, so that the m
AfilCa [17]

Answer: length of B =4.00

Explanation:

for  the vectors A and B and the angle between them as  x.

Magnitude of the sum of A and B is  given as = √(A²+B²+2ABcosx

where

Magnitude of A  = 3.00

Magnitude of the sum of A and B is  5.00

5.00=√(A²+B²+2ABcos90°

5.00= √3² +b² +0

5²= 3² +b²

25=9+b²

b²= 25-9

b² = 16

b=  √16

b= 4
