Answer:
the gravitational force is proportional to the mass of both interacting objects, bigger objects will attract each other with a greater gravitational force. So the mass of either object increases, the force of gravitational attraction between them also increases.
Answer:
d = 20.89 g/cm³
Explanation:
Given data:
Length of block = 4.20 cm
width of block = 3.80 cm
Height of block = 5.40 cm
Mass of block = 1800 g
Density of block = ?
Solution:
First of all we will calculate the volume.
V = l×w×h
V = 4.20 cm ×3.80 cm× 5.40 cm
v = 86.18 cm³
Density:
d =m/v
d =1800 g/ 86.18 cm³
d = 20.89 g/cm³
8. <span>The number of protons in the nucleus of an element is called its atomic number.
9. </span><span>If two or more compounds are composed of elements A and B, the ratio of the masses of B combined with 1 g of A is always a ratio of small whole numbers. This is a statement of the law of definite proportions.

Answer: 
is a hydrocarbon.
Explanation:
Alcohols are the compounds which contain -OH as the functional group. Example: 
Amine are the compounds which contain 
as the functional group. Example: 
Ether are the compounds which contain 
as the functional group. Example: 
Hydrocarbons are defined as the compounds in which bonds are present between carbon and carbon atoms. Hydrocarbons with single bond between carbon and carbon atoms are called as alkanes.The general formula for alkanes is 
Example: which is named as hexane.
