3. Which of the following statements regarding sunspots is NOT correct?

Question

a. the pattern of the magnetic polarity of the spots repeatgs about every 22 years.
b. Sunspots appear in pairs because they form when the magnetic field kinks and breaks through the photosphere.
c. The sunspots are heated by the magnetic field to a temperature of 4800 K above their surroundings in the photosphere.

Answer 1

1) The cycle is 22 years: one 11 year cycle of one polarity, followed by the next 11 year cycle with the reverse polarity.
"Hale suggested that the sunspot cycle period is 22 years, covering two polar reversals of the solar magnetic dipole field." (wiki)


2) Often (but not always), "prototypical sunspots come in pairs with opposite magnetic polarity" (wiki)

3) A sunspot is "marked by a lower temperature than its surroundings" (wiki)

Answer 2

First of all I thought b because sunspots dont necessarily appear in pairs,but then I looked at c and dont think that sunspots would'nt be a temp of 4800 k because they are burnt out gas patches and aremuch cooler.

Answer 3

y = x^3 - 3x^2 - 3x + 9 happily for us, we can element this by making use of grouping. team the 1st 2 words and the final 2 words. y = x^2(x - 3) - 3(x - 3) element by making use of grouping. y = (x - 3)(x^2 - 3) Telling us we've zeros at 3, sqrt(3), and -sqrt(3). At this factor, all of us understand the respond is the two going to be A or B. sqrt(3) is approximately a million.seventy 3, so -sqrt(3) is approximately -a million.seventy 3 sounds like the respond can the two be A OR B. Did you mistype?

Answer 4

A, The pattern repeats every 11 years

Answer 5

Though I can not back it up my answer would be B is incorrect.

Answer 6

both 'A' and 'C' are incorrect statements.
