Answer:
It keeps particles that make up protons and neutrons together.
Explanation:
Nuclear force is a short range of force which means it will act at short range of distance like fermi order distance.
This shows the order of radius of the nuclei which means all the neutrons and protons which resides into the nucleus will exert the nuclear force on each other and this nuclear force is of large magnitude compare to electrostatic force or gravitation force between them.
While if the distance is more than the fermi order distance then the nuclear force totally disappears so it will not exist for large distances.
so here the correct answer must be
It keeps particles that make up protons and neutrons together.
Terminal velocity is the point when an accelerating object reaches a constant speed. When an object is in free fall on earth, this happens due to the drag force of the atmosphere that pushes up on the object.
If the earth had no atmosphere, the object would keep accelerating and never reach terminal velocity due to the lack of air drag.
Answer:
Maximum height reached by the bullet = 4.01 m
Explanation:
Horizontal displacement = 92 m
Time taken = 6.4 s
Horizontal velocity
We have angle of projection = 32°
Horizontal velocity = u cos 32 = 14.375
u = 16.95 m/s
Vertical velocity = u sin θ = 16.95 x sin 32 = 8.98 m/s
Time of flight till it reaches maximum height = 0.5 x 6.4 = 3.2s
Now we have vertical motion of bullet
S = ut + 0.5 at²
Vertical velocity = u = 16.95 m/s
a = -9.81 m/s²
t = 3.2s
Substituting
S = 16.95 x 3.2 - 0.5 x 9.81 x 3.2² = 4.01 m
Maximum height reached by the bullet = 4.01 m
