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.

Answer:
Carbon will become positively charged.
The charge of Carbon will be +4.
Explanation:
The charge of Carbon will be +4.
In the periodic table, elements that give out or lose electrons during electrochemical combinations are called electropositive elements. If carbon loses electrons during the chemical combination, Carbon will become positively charged, with a valency equal to the number of electrons that it lost.
This will make carbon have a charge of +4
Answer:
5.865 μs
Explanation:
t₀ = Time taken to decay a muon = 2.20 μs
c = Speed of Light in vacuum = 3×10⁸ m/s
v = Velocity of muon = 0.927 c
t = Lifetime observed
Time dilation

∴Lifetime observed for muons approaching at 0.927 the speed of light is 5.865 μs
Answer:

Explanation:
The acceleration due to gravity on earth is
regardless of the mass of the object. This means, in the absence of air resistance, both a 3000 kg object and a 300 kg will accelerate at the same rate of
towards earth.
The reason the acceleration due to gravity is the same for all masses is that by grace of nature, the inertial mass
of the object from
equals the gravitational mass
from
, resulting


which is the acceleration that only depends on the mass of earth and its radius, and not on the mass of the object.
