The correct choice is C .
Technically, choice-A is the process involved. But it's already been done,
and widely published, and the spectrum of every element is easily available.
For you to take the time and go to the trouble of constructing the spectra
would be like inventing wheels if you want to ride a bicycle.
Answer:
For uniform acceleration
a = (v2 - v1) /t = 2.5 acceleration is constant 2.5
v2 = 2.5 * 4 v1 = 0 at t = 0
v2 = 2.5 m/s^2 * 4 s = 10 m/s
<span>The answer is 62 u. The molecular mass of a molecule (Mr) is the sum of atomic masses (Ar) of its elements. Ar(Na) = 23 u. Ar(O) = 16 u. Therefore, the molecular mass of sodium oxide is 62 u: Mr(Na2O) = 2 * Ar(Na) + Ar(O) = 2 * 23 u + 16 u = 46 + 16 = 62 u.</span>

Answer:
Explanation:
From the question we are told that:
Weight 
Altitude 
Let
Radius of Earth 
Gravity 
Generally the equation for Gravity at altitude is mathematically given by
Therefore
Weight at sea level
Weight at 6.33 altitude
Therefore
