All of the sun’s energy is produced in its core through:
a. fusion
c. hydrolysis
b. fission
d. hydrogenation

The correct answer is Option a.

Explanation:

Sun's core is mainly made up of hydrogen and helium. In the Sun's core, nuclear fusion reaction takes place which converts hydrogen into helium releasing a massive amount of energy which radiates to the surface of the Sun and then in the solar system.

Reactions for the nuclear fusion of Hydrogen to helium follows:

Hence, the correct answer is option a.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
