The volume of an object that has a mass of 16 g and a density of 12 g/cm³ is 1.33cm³.
<h3>How to calculate density?</h3>
Density is a measure of a substance mass in relation with it's volume, which means that it can be calculated by dividing the mass of the substance by volume as follows:
Density = mass ÷ volume
According to this question, an object has a mass of 16 g and a density of 12 g/cm³. The volume can be calculated as follows:
Volume = 16g ÷ 12g/cm³
Volume = 1.33cm³
Therefore, the volume of an object that has a mass of 16 g and a density of 12 g/cm³ is 1.33cm³.

Answer:
(That an object must be made out of metal to be attracted, but not all metals are attracted.) Metals such as iron, nickel, and cobalt are attracted to magnets. Steel has iron in it, so it is also attracted to magnets.
Explanation:
basically magnets
Answer: The angle of inclination is nearly 30°
Explanation:
For a body on an inclined plane, the coefficient of friction between the body and the plane is equal to the ratio of the moving force applied to the body to the frictional force acting on the body.
If uK coefficient of friction;
Fm is the moving force
R is the normal reaction on the body
Mathematically uK = Fm/R
Fm = WSin(theta)
R = Wcos(theta)
uK = Wsin(theta)/Wcos(theta)
uK = tan(theta)
theta = arctan(uK)
If uK is 0.58
theta = arctan0.58
theta = 30°
The angle of the inclined will be 30°
