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;
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.
Scalar quantities have only a magnitude. So the answer is scalar quantities.
Well one is from potential energy to ascensive moving energy . And another is from electrical to circuit energy.
<span>A spring balance will give a different mass reading on the Moon from that on Earth. A beam balance however, will give the same reading.Explain why.

<span>Beam Balance:
Beam balance measures mass.
Mass is the amount of matter the object has.
The S.I. unit of mass is kg

Spring Balance:
Spring balance measures weight not mass.
Disadvantage: It requires gravity to measure.
The S.I. unit of weight is newton (N).
That is why when we are in outer space, we become lighter-there is less gravity!</span>
Mass remains constant while weight is dependent on the gravitational pull of the planet. Mass only changes with a change in matter that results in a change of volume.
<span>Mass remains constant throughout. Only weight changes with gravitational acceleration. Mass will only change with a change in the volume of matter in the body.</span>
