The question is:
<h2>What is the distance of the object from the mirror?</h2>
To answer this question, you must learn that, for plane mirrors, the distance of the object from the mirror is equal to the distance of the image formed behind the mirror.
For instance if you stand 1 meter away from a mirror (a plane one) the position of the image of you will be 1 meter behind the mirror.
Here, the initial distance between the image and the object is 40 cm. Then, the distance between the image and the miror is 20 cm, such as it is the distance between the object and the mirror.
That the distance of the object is reduced by 9.2 cm, must be understood as that the object was placed 9.2 cm closer to the mirror.
Then, the new distance of the object from the mirror is 20 cm - 9.2 cm = 10.8 cm. ← answer

Quartz has the formula SiO2
From the periodic table:
mass of oxygen = 16 grams
mass of silicon = 28.0855 grams
Mass of one mole of quarts = 28.0855 + 2(16) = 60.0855 grams
number of moles = mass / molar mass
number of moles = 1.6 / 60.0855 = 0.0266 moles
Each mole of quartz contains Avogadro's number of atoms.
Therefore:
number of atoms in 1.6 g = 1.6 x 6.02 x 10^23 = 1.603 x 10^22 atoms
Answer:
<u>Solubility of the liquid increases with temperature.</u>
Explanation:
The solubility of the liquid increases with increase in the temperature but there is no effect of the pressure on the solubility of a liquid, whereas, the solubility of gases in liquids increases on increasing the pressure above above the surface of the liquid.
On increasing temperature of a liquid solvent the kinetic energy of the particles of the solvent increases which makes particles to move faster which breaks the particles of the solute more rapidly with more energy.
Also the saturation point of a solvent can be increased by increasing the temperature of it which allows to dissolve more solute in the solvent beyond the saturation point.
