Answer: Weight
Explanation:The mass of an object is a measure of the quantity of matter in the object. This quantity remains constant under any circumstance.
However, the same cannot be said about the weight of such object.
The weight of the object is very much dependent on the acceleration due to gravity which is a accelerational pull (by convention-- a pull downwards).
This is why an object tends to fall when it is thrown upwards on the earth for instance.
The statements above consequently infer that since the gravitational field of Jupiter is greater than that of the earth, the acceleration due to gravity on Jupiter is greater than that on earth.
And since the weight of an object(W) is a product of its mass and the acceleration due to gravity at that point.
Consequently, the object's weight on Jupiter would be greater than its weight on earth.
Please note; The Mass of the object remains constant everywhere.
Answer:venus
Explanation:
is most like Earth in terms of mass and size, and it is also the planet closest to Earth, but the two planets are far from identical twins.
Answer:
False
Explanation:
Let's consider the definition of the angular momentum,
where 
is the moment of inertia for a rigid body. Now, this moment of inertia could change if we change the axis of rotation, because "r" is defined as the distance between the puntual mass and the nearest point on the axis of rotation, but still it's going to have some value. On the other hand,
so 
unless 
║ 
.
In conclusion, a rigid body could rotate about certain axis, generating an angular momentum, but if you choose another axis, there could be some parts of the rigid body rotating around the new axis, especially if there is a projection of the old axis in the new one.
