Question

which of the following statements about the sunspots & the sunspot cycle is not true? more sunspots, flares, & coronal mass ejections are found at the cycles peak. with each subsequent peak, the magnetic polarity of the sun is reversed. the rate of nuclear fusion in the sun peaks every 11 years. sunspots are darker because they are cooler than their surroundings.

Explanation:

The sunspot cycle is about 11 - year long, during which more sunspots, flares, and coronal mass ejections occur at the peak. The Sun's magnetic polarity reverses with each peak, and sunspots are darker due to being cooler. However, the rate of nuclear fusion in the Sun is relatively stable and not directly related to the 11 - year sunspot cycle.

Answer:

The rate of nuclear fusion in the Sun peaks every 11 years.
