How does the Sun release nuclear energy?
2 answers:
Answer: (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.

Answer:
The displacement is zero miles
Explanation:
The displacement of an object that moves from point A to point B is defined as
Where d is the displacement of the object. The displacement does not depend on the trajectory of the object. It only depends on the linear distance between the end point and the starting point.
In this case we know that the person walks from home to work and then walks from work to home. Therefore, the total displacement is the linear distance between the point where its journey begins and the point where the route ends.
The tour begins on the front porch of your house and ends on the front porch of your house (when you return from work). If we call A to the front porch of the house then the displacement is:
The displacement is zero miles, since the person finishes the journey just where it started (front porch)
