Answer:
371.2 mm
Explanation:
The Balmer series of spectral lines is obtained from the formula
1/λ = R(1/2² -1/n²) where λ = wavelength, R = Rydberg's constant = 1.097 × 10⁷ m⁻¹
when n = 15
1/λ = 1.097 × 10⁷ m⁻¹(1/2² -1/15²)
= 1.097 × 10⁷ m⁻¹(1/4 -1/225)
= 1.097 × 10⁷ m⁻¹(0.25 - 0.0044)
= 1.097 × 10⁷ m⁻¹ 0.245556
= 2.693 10⁶ m⁻¹
So,
λ = 1/2.693 10⁶ m⁻¹
= 0.3712 10⁻⁶ m
= 371.2 mm
Answer: 
Explanation:
In the image attached with this answer are shown the given options from which only one is correct.
The correct expression is:
Because, if we derive velocity 
with respect to time 
we will have acceleration 
, hence:
Where 
is the mass with units of kilograms (
) and with units of meter per square seconds 
, having as a result 
The other expressions are incorrect, let’s prove it:
This result has units of 
This result has units of
This result has units of 
and 
is a constant
This result has units of
This result has units of
This result has units of 
and is a constant
This result has units of 
and is a constant
because 
is a constant in this derivation respect to
This result has units of 
and is a constant
Answer:
Observation 1 represents a solar wind because solar winds are a continuous stream of particles given off by the sun.
Explanation:
Answer:
no
Explanation:
An electron is one of the components of an atom, so it cannot be larger than that.
