Answer:
8 electrons in the third energy level
Explanation:
From the description,the third energy level has 8 electron (represented by the small green balls you describe)
It does work or increases thermal energy
Answer;
1 second
Explanation;
Two objects moving at the same speed will always stay the same distance apart. If two objects are moving at different speeds, the distance between them must change.
Therefore; if the distance will be the same and the speed is also the same then the time taken will be the same.
Answer:
from vacuum to air
Explanation:
Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.
- When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
- Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.
The correct option must be from a less dense medium to a denser medium.
density of glass = 2500 kg/m³
density of air = 1.275 kg/m³
density of ice = 919 kg/m³
density of water = 1000 kg/m³
density of plastic = 940 kg/m³
density of vacuum = 6.5 x 10⁻²⁷ kg/m³
The two possible options are;
from ice to water
from vacuum to air
The difference in densities of ice and water is not larger compared to vacuum and air.
If you are required to choose two options, the two options are correct
But if it is only one option, then from vacuum to air is the correct answer.
Therefore, the correct option is from vacuum to air
