1)density
2)11.2/8 g/cm*3
3) in order 2 3 1
4) mass
5) all of them except 4 is right
Explanation:
Solution 1:
Roland is measuring Density. Density is mass per unit volume. If you look at the reading: 3.12 g/cm³, it is mass per unit volume as grams (g) is a unit of mass and cm³ is a unit of volume.
Solution 2:
Mass = 11.2 g
Length of sides = 2cm
Thus volume = (Length)³
Volume = (2)³ = 8 cm³
Thus, Density will be,
[tex]Density = \frac{Mass}{Volume}[/tex]
[tex]Density = \frac{11.2}{8}[/tex]
Density = 1.4 g/cm³
Solution 3:
Volume: It is a measure of the amount of space that a substance or an object takes up.
Mass: It is a measure of the amount of matter in a substance or an object.
Weight: It is a measure of the force generated by gravity.
Solution 4:
Mass of block A and B are same.
We know that,
Weight = Mass × (Acceleration due to gravity)
It implies that the weight is not same for both the blocks. As gravity on the Moon is 6 times less than that on Earth.
Their size is different that means their volume is different
Since, volume and mass are different their density is also different.
Solution 5:
Matter has mass.
It takes volume.
All the matter is made up of atoms and compounds.
The volume depends on the the size which can differ so density will not be same for all the matter.
