Answer:
Explanation:
The difference between the water level in the eudiometer tube and the water level in the beaker must be measured because we have to put into consideration, the pressure of the gases in the eudiometer tube. This said pressure of gas in the eudiometer must equal the atmospheric pressure. If or by chance, the water levels happens not to be at the same height, then this is not the case. And then, as a result, in order to account for the difference between both, while also being able to get accurate results, you have to find the difference or subtract the water levels and then go ahead in converting them to mmHg.
A continuous spectrum contains all the wavelengths
A discontinuous spectrum has strips of specific colors and can be used to identify the elements making it.

Acceleration equals 24 km/s
Average equals 396km/s
Answer:
0.00288 J
Explanation:
We know that
W= Fds
F = −α∆s^4
α = 45 N/m^4 and ∆s = displacement
W= −α∆s^4ds
integrating both the sides from s= 0 to 0.2
W= 45/5×0.2^5= 0.00288 J
Take a small burning candle. ... After few minutes the candle is extinguished. As the supply of air is stopped due to glass jar the burning of candle is also stopped. This experiment proves that air supports burning.
