The equation for the speed of an electromagnetic wave is
igomit [66]

Answer:

c = 1 / √(ε₀*μ₀)

Explanation:

The speed of the electromagnetic wave in free space is given in terms of the permeability and the permittivity of free space by

c = 1 / √(ε₀*μ₀)

where the permeability of free space (μ₀) is a physical constant used often in electromagnetism and ε₀ is the permittivity of free space (a physical constant).

When an excited electron in a hydrogen atom falls from the n = 3 to the n = 2 level, a photon of red light is emitted from the a
Kaylis [27]

Answer: 653.33 nm ; 1875, 24 nm

Explanation: For the first case we have to use the Balmer series for  the hydrogen  when the atom falls from the n = 3 to the n = 2. So for the second transtions for the hydrogen we use  the Paschen serie.   To do  the calculation we need to know  the Ryberg constant that is equal to 1.097 * 10^7 m^-1. In the attach is shown the expression for spectral series used for calculation.

A van slows down as it travels up a steep hill. Its speed goes from 20m/s at the bottom of the hill to 12m/s when it reaches the
Paladinen [302]
The van's AVERAGE speed on the way up the hill is

(1/2) (20 + 12) = (1/2) (32) = 16 m/s .

At an average speed of 16 m/s, it travels

(16 m/s) x (8 s) = 128 meters in 8 seconds.
