When a low-pressure gas of hydrogen atoms is placed in a tube and a large voltage is applied to the end of the tube, the atoms w

Veronika [31]

Answer:a) λ = 4.862 10⁻⁷ m, b) λ = 4.341 10⁻⁷ m

Explanation:

The spectrum of hydrogen can be described by the expression

in the case of the initial state n = 2 this series is the Balmer series

a) Find the wavelength for n = 4

let's calculate

= 1,097 10⁷ ()

\frac{1}{ \lambda} = 1.097 10⁷ 0.1875 = 0.2056 10⁷

λ = 4.862 10⁻⁷ m

b) n = 5

\frac{1}{ \lambda} = 1,097 10⁷ ()

\frac{1}{ \lambda} = 1.097 10⁷ 0.21 = 0.23037 10⁷

λ = 4.341 10⁻⁷ m

Analysis of the relationship between the fuel economy (mpg) and engine size (liters) for 35 models of cars produces the regres

kvasek [131]

Answer:

Gas mileage is 17.29

Explanation:

Given data:

The total number of the model is 35

The total size of the engine is 5 ltr

The regression model is given as

$36.44 - 3.829\times engine\ size$

From the information given in question we have

Regression equation is : model- mpg $= 36.44 - 3.829\times engine\ size$

Therefore for engine capacity of 5 liters;

Gas mileage $= 36.44 - 3.829\times 5 = 17.29$

Gas mileage is 17.29
