A candle placed between two plane mirrors inclined at an angle of 45 degrees will form 7 images. This is due to multiple reflections between the mirrors. The number of images depends on the angle between the mirrors.
In physics, when a candle is placed between two plane mirrors inclined at an angle of 45 degrees, 7 images will be formed. This happens due to multiple reflections between the mirrors. As per the formula for number of images n = 360/θ - 1, where θ is the angle between the mirrors, for an angle of 45 degrees, we get n = 360/45 - 1 = 7. The actual number of images can be less than this if they overlap each other.

gas ➡ solid
gas ➡ liquid
solid ➡ gas
Answer: solid ➡ gas
Explanation:
Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another. and thus have least kinetic energy.
For example : Copper
Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.. they have intermediate kinetic energy between solids and gases.
For example : water
Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out. They have highest kinetic energy.
For example : Helium gas
Answer:
Selenium (Se)
Explanation:
To identify an element, we look at its number of protons.
We are given 32 protons, so the 32nd element of the Periodic Table is Selenium (Se).
