Answer:
Because it is the result of two more fundamental units, a derived unit is termed that. For volume, the cubic meter (m³) is the fundamental unit of area. Any number that cannot be measured directly with any equipment is referred to as a derived unit. For example, we can't quantify a substance's density using a rule, scale, or bucket.

Answer:
Yes
Explanation:
The density of the object does not change when it is broken in more pieces, therefore Maria will be able to find the density of the material.
In fact, by breaking the object, then she can take only one piece, and by measuring the mass of this piece and its volume she will be able to calculate the density of the material by using the formula:
where
m is the mass of the piece
V is its volume
d is the density
And the density will be the same for every piece, since they are made by the same material, and the density depends only on the properties of the material itself.
Action force is your weight pushing down on the chair. The reaction force is the force exerted by the chair that pushes up on your body and is equal to your weight. objects have inertia.
