Answer:

The homogeneous mixture is only in the one phase of matter, whereas heterogeneous mixture is always in two or more than two different phases of matter. Solutions are termed as the homogeneous mixtures, on the other hand, suspensions or colloids are termed as the heterogeneous mixtures.

Examples:

Homogeneous:

Bronze: this alloy is an example of homogeneous substances since it is composed of tin and copper.

Milk : this mixture that we see in a uniform way is composed of substances such as water and fats.

Heterogeneous:

Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.

If the moon has grown to twice its size, the gravitational force of the Earth on the Moon would be twice as much, since the gravitational force is proportional to the masses of both the Earth and the Moon.
