Answer and Explanation:
The computation of the shortest wavelength in the series is shown below:-
Where
represents wavelength
R represents Rydberg's constant
represents Final energy states
and 
represents initial energy states
Now Substitute is
now we will put the values into the above formula
Now we will rewrite the answer in the term of
So, the whole Paschen series is in the part of the spectrum.
Explanation:
1. Force applied on an object is given by :
F = W = mg
(a) A 160 lb human being, F = 160 lb
g = acceleration due to gravity, g = 32 ft/s²
m = 5 kg
(b) A 1.9 lb cockatoo, F = 1.9 lb
m = 0.059 kg
2. (a) A 2300 kg rhinoceros, m = 2300 kg
(b) A 22 g song sparrow, m = 22 g = 0.022 kg
Hence, this is the required solution.
Answer:
(a) 2.3 x 10^-12 N
(b) 1.6 x 10^5 m/s
Explanation:
q1 = 1.6 x 10^-19 C
q2 = 1.6 x 10^-19 C
r = 1 x 10^-8 m
(a) the electrostatic force is given by
F = K q1 x q2 / r^2
F = ( 9 x 10^9 x 1.6 x 10^-19 x 1.6 x 10^-19) / (1 x 10-^-8)^2
F = 2.3 x 10^-12 N
The force is attractive in nature because the nature of charge on electron and proton s opposite to each other.
(b) The electrostatic force is balanced by the centripetal force actig on the electron.
F = mv^2 / r
where, r be the radius of orbit and v be the velocity of electron in the orbit.
2.3 x 10^-12 = (9.1 x 10^-31 x v^2) / (1 x 10^-8)
v = 1.6 x 10^5 m/s
