Answer:
Explanation:
Nuclear Fission -
The process of the splitting of atom , by radioactive decay process or by any collisional impact .
Sun contains many radioactive isotopes like , thorium , uranium , etc .
The nuclear fission process is an intrinsic property of the radioactive nuclides.
Nuclear Fusion -
The process , where two or more than two atomic nuclei combines to form one or more different atomic nuclei and subatomic particles .
The energy released in both the process is almost same ,
But on the surface of Sun , hydrogen is abundantly present , hence , hydrogen fusion is possible , so the dominant source of energy on the sun is Fusion .

Answer:
Explanation:
Newton's First law of motion: An object is in motion, it remains in motion or an object is at rest it remains at rest until and unless an external force is not applied on the body.
For example, a car is at rest, it remains at rest as there is no external force is applied on the body.
Newton's Second law of motion: The rate of change of momentum of the object is directly proportional to the force applied on the object.
Force proportional to the rate of change in momentum.
Newton's Third law of motion: For every action, there is an equal and opposite reaction.
Action and reaction force acting on two different bodies.
Answer:
The angular momentum of the particle is 58.14 kg m²/s along positive z- axis and is independent of time .
Explanation:
Given that,
Mass = 1.70 kg
Position vector
We need to calculate the angular velocity
The velocity is the rate of change of the position of the particle.
We need to calculate the angular momentum of the particle
Using formula of angular momentum
Where, p = mv
Put the value of p into the formula
Substitute the value into the formula
Hence, The angular momentum of the particle is 58.14 kg m²/s along positive z- axis and is independent of time .
