why are bricks burnt in kilns

they arnt burnt, they are baked, it increases the hardness and water resistasnce over just letting them sit and dry.

Bricks are ceramics. They have to get to a high temperature before the silica in the bricks melts and bonds together to make it strong

Thanks bob, the word cilica evaded my conciousness.

thanks ken and bob for your prompt answer

Light is incident on a plane mirror at an angle of 46 degrees relative to its surface. What i the angle of reflection?

gave me a sentences for abolitions?

To find the angle of reflection when light is incident on a plane mirror, we need to apply the law of reflection. The law of reflection states that the angle of incidence is equal to the angle of reflection.

In this case, the given angle of incidence is 46 degrees. Therefore, the angle of reflection will also be 46 degrees.

To verify this, you can perform a simple experiment. Place a plane mirror on a table and shine a light beam at an angle of 46 degrees to its surface. Observe the reflected light beam, and you will see that it forms an angle of 46 degrees with the surface of the mirror.

Now, I noticed that you mentioned "gave me a sentences for abolitions?" The phrase you provided is incomplete and does not make sense. Could you please provide more details or rephrase your request?
