Answer:
1024Å
Explanation:
The Rydberg equation is an empirical relationship equation expressed by Balmer and Rydberg which is given as:
1/λ = 
.............................(1)
where 
is the Rydberg constant given as 
, n is the transition level and the subscript f and i show the final and initial level numbers respectively. λ is the wavelength.
= 1
Using equation (1), we have
1/λ 
= 
= 
= 
= - 9763300
λ = 
= 
We should note that the negative sign we have is as a result of photon absorption whereby the hydrogen atom gains energy to undergo a transition from the lower energy level to a higher one. Wavelength does not have a negative value.
To convert to Å, we have
λ = 
= 1024Å
Therefore the wavelength of the photon in Å is 1024Å
The correct answer is option B. Alpha radiation is identical in mass and charge to a helium nucleus. Alpha particle contains two protons and neutrons. It is the same as giving out a doubly-ionized helium atoms.
Water, food, shelter, oxygen, a steady temperature.
here's five, just pick 4, good luck :)
Answer:
3m/s²
Explanation:
Force applied to an object can be calculated thus;
F = ma
Where;
F = force applied (Newtons)
m = mass of substance (kg)
a = acceleration (m/s²)
According to the information provided in this question, F = 12.0 newtons, m = 4.0 kg, a = ?
Derived from F = m.a
We have; a = F/m
a = 12/4
a = 3
The resultant acceleration of the object is 3m/s².
