Answer:
a) The strength of gravity decreases if one moved away from Jupiter
b) The strength of gravity increases if one fell into Jupiter
Explanation:
The gravitational attraction is given by Newton law of gravitation as follows;
![Force \ (strength) \ of \ gravity = \dfrac{G \times M \times m}{R^2}](https://tex.z-dn.net/?f=Force%20%5C%20%28strength%29%20%5C%20of%20%5C%20gravity%20%3D%20%5Cdfrac%7BG%20%5Ctimes%20M%20%5Ctimes%20m%7D%7BR%5E2%7D)
Where;
G = The universal gravitational constant = 6.67408 × 10⁻¹¹ m³/(kg·s²)
M = The mass of Jupiter
m = The mass of the nearby body
R = The distance between the centers of Jupiter and the body
From the equation, we have that the gravitational strength varies inversely with the square of the separation distance between two bodies
Therefore, as one moves away, R increases, and the strength of gravity reduces
Similarly as the body falls into Jupiter, R, reduces the gravitational strength increases.
The correct answer to the question is : 7 m/s.
EXPLANATION:
As per the question, the apple is at a height h = 2.5 m.
The initial velocity of the apple u = 0
We are asked to calculate the final velocity [ v ] of the apple before touching the ground.
As the apple is falling under gravity, then the acceleration produced on the apple is nothing else than acceleration due to gravity.
Hence, acceleration a = g = ![9.8\ m/s^2](https://tex.z-dn.net/?f=9.8%5C%20m%2Fs%5E2)
From equation of kinematics , we know that -
![v^2-u^2\ =\ 2as](https://tex.z-dn.net/?f=v%5E2-u%5E2%5C%20%3D%5C%202as)
⇒ ![v^2=\ u^2+2gh](https://tex.z-dn.net/?f=v%5E2%3D%5C%20u%5E2%2B2gh)
⇒ ![v^2=\ 0^2+2\times 9.8\times 2.5](https://tex.z-dn.net/?f=v%5E2%3D%5C%200%5E2%2B2%5Ctimes%209.8%5Ctimes%202.5)
⇒ ![v^2=\ 49](https://tex.z-dn.net/?f=v%5E2%3D%5C%2049)
⇒ ![v=\ \sqrt{49}\ m/s](https://tex.z-dn.net/?f=v%3D%5C%20%5Csqrt%7B49%7D%5C%20m%2Fs)
⇒
[ans]
Hence, the final velocity is 7 m/s.

A light bulb lightning up
Explanation:
Interstellar gas clouds are common in many galaxy, like the Orion nebulae which many young stars are being born. A typical nebula is many light years in diameter and contains enough material mass to make several thousand stars the size of our sun. The majority of the gas in nebulae consist of molecules of hydrogen and helium-but most nebulae also contain atoms of other elements. All known element in our periodic table is also being made inside this crucible of this immense hot gas. The source of the organic molecules is still a mystery. Irregularities in the density of the gas causes a net gravitational force that pull the gas molecules close together.
