Answer 1

A force can produce the following effects

_______________________

⭐A force can move a stationary object.

⭐A force can stop a moving object.

Homogeneous Mixture

--------------------------------

⭐These are the types of mixtures in which the components mixed are uniformly distributed throughout the mixture. In other words, “they are uniform throughout”. We can observe only one phase of matter in a homogeneous mixture. Key points regarding such mixtures are:

⭐Particles are distributed uniformly

⭐We can’t judge a homogeneous mixture by just seeing it

⭐Homogeneous mixtures are also called solutions

⭐Uniform composition

Example: rainwater, vinegar, etc.

Heterogeneous Mixture

-------------------------------

⭐This is a type of mixture in which all the components are completely mixed and all the particles can be seen under a microscope. We can easily identify the components and more than one phase can be seen by naked eyes.

⭐Key points regarding this type of mixture:

⭐Particles are distributed non uniformly

⭐We can judge a heterogeneous mixture by just seeing it

⭐Non-uniform composition

Example: seawater, pizza, etc.

Answer 2

Answer:

12) the two effects of force are

I) It can change the state of movement of the body on which force is applied,

(ii) It can change the shape and size of an object.

13) A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution. A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.
