Answer:
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts
Explanation:
The downwards component of weight of the object would be 35sin25 degrees = 14.8
F=14.8 - 8 = 6.8 N m= 35/9.8= 3.57 kg
F=mA
Therefore,
3.57A= 6.8 N
=> A= 6.8/3.57
=> A= 1.902 ms^-2
F(max)= (U)R where (U)= coefficient of friction
and R= Normal reaction force
R= 35cos25
= 31.72 N
Since, F(max)= 8
8= (U)* 31.72
=>(U)= 8/31.72
=>(U)= 0.25
The correct option is (b) Sea breeze
During the day, susan notices that the wind is blowing onshore at the beach called sea breeze.
What is sea breeze?
- Any wind that flows from a big body of water onto or onto a landmass is called a sea breeze or an onshore breeze.
- Sea breezes form as a result of changes in air pressure brought on by the different heat capacities of water and dry land. Sea breezes are therefore more confined than prevailing winds.
- A sea wind is frequently seen along coasts after sunrise because land warms up far more quickly than water does when exposed to solar radiation.
- The sea wind front is significant because it can serve as a catalyst for afternoon thunderstorms and provide welcome cooling along the coast.

The Cosmic Ray is a natural way for nuclear fission and nucleosynthesis to occur. It refers to the formation of chemical elements from the impact of cosmic rays on an object.
Displacement = 0, assuming that he runs back to original position
Average velocity is displacement/ time, since displacement =0, velocity is also 0
