As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
Answer:
The reason is to allow the thermometer to respond relatively quickly, and relatively accurately. The glass contains the liquid being used in the thermometer, but if it is too thick, then it will not pass heat as quickly, and it will absorb some of the heat from whatever is being measured.

Answer:
Cuolomb is SI unit of charge
1 e=1.6022E-19 C
1 C = 6.2415E+18 e
Explanation:
Coulomb(C) is the SI unit for measuring electric charge and is given as the product of current and time. To convert Cuolomb to electron, we multiply each cuolomb of charge by 1 C = 6.2415E+18 e while to convert electron into charge, we multiply the electrons by 1e=1.6022E-19 C
