How does the sun release nuclear energy?

through the fusion of a uranium nucleus into smaller nuclei
through the fusion of hydrogen nuclei into a heavier nucleus
through the fission of a uranium nucleus into smaller nuclei
through the fission of hydrogen nuclei into a heavier nucleus

(B) through the fusion of hydrogen nuclei into a heavier nucleus.

Explanation:- Because of the intense temperature and pressure on the surface of the sun, nuclear fusion takes place. Hydrogen nuclei fuse together to generate helium producing heat and light energy alongside.

The fusion thus produces large amount of heat energy which is radiated out from the sun outside.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
