What statements accurately describe sunspots? check all that apply.

sunspots are storms on the sun’s surface.
sunspots are marked by intense magnetic activity.
sunspots produce solar flares and hot gassy ejections.
sunspots can affect earth’s climate.
sunspots are cool areas where the sun is covered by clouds.

A sunspot is a temporary phenomenon caused by intense magnetic fields, it's a darker area that also indicates a lower temperature than the rest of the surface. A sunspot is also a storm on the Sun's photosphere, which is the outer shell.

An important application of sunspots is that they help to determine space weather and the state of our ionosphere, which can affect Earth. In addition, sunspots can produce explosion of energy towards the space, which is caused by these intense magnetic fields. This explosions are called solar flares.

Therefore, according to its definition, sunspots can be described with the following statements:

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

pe = weightxheight = 2000x1000=2,000,000joules
