If a hydrogen atom has its electron in the n= 4 state, how much energy in eV is needed to ionize it?
ololo11 [35]

Answer:

Explanation:

Energy of electron in n = 4 state

= - 13.6/4² =- 0.85 eV

So energy needed to extract it from atom = .85 eV.

What will happen to the pitch of a sound as that sound’s source approaches an observer? Explain why this happens, based on what
I am Lyosha [343]

The pitch of a sound is decreased, when a sound source approaches the observer.

<u>Explanation:</u>

Pitch is nothing but it is a property that helps to determine whether the sound is high or low. Doppler effect helps to understand this concept easily. The pitch of the sound is mainly calculated based on the frequency of the sound wave arose from the sound source.

As the wellspring of sound waves moves toward an audience, the sound waves draw nearer together, expanding their recurrence and the pitch of the sound.

Dante drew a diagram of an electric generator.
dimaraw [331]

Answer: There should be one brush on each slip ring.

Explanation:

A device that converts mechanical energy into electrical energy is known as an electric generator. The magnets are kept surrounding armature and axle. The armature rotates in between the magnets. This generates electric current which is detected by the ammeter.

It is based on Faraday's law - when a conductor moves in a magnetic field, an emf is induced in the conductor. Thus, a battery is not required. There should be one brush on each slip ring because the brushes must make contact with the rotating rings to supply current to the coil.

At a beach the light is generallypartially polarized owing to reflections off sand and water. At a particular beach on a particu
Ne4ueva [31]

Answer:

a) 0.159

b) 0.84

Explanation:

The Horizontal component is 2.3 times the vertical component

Let the horizontal electric field component = E_{h}

Let the vertical electric field component = E_{v}

The formula for light intensity is given by:

I = \frac{E_{m} ^{2} }{2c \mu}..............................(1)

E_{m} is the resolution of the vertical and horizontal components, E_{h} and    E_{v}

E_{m} ^{2} = E_{h} ^{2} + E_{v} ^{2}..................(2)

Light intensity before the glasses were put on:

I_{1}  = \frac{E_{m} ^{2} }{2c \mu_{1} }.............................(3)

Put equation (2) into equation (3)

I_{1}  = \frac{E_{h} ^{2} + E_{v} ^{2}}{2c \mu_{1} }.............................(4)

After the glasses were put on the horizontal component vanishes, i.e. E_{h} = 0

I_{2}  = \frac{ E_{v} ^{2}}{2c \mu_{2} }...................................(5)

Divide equation (5) by equation (4)

\frac{I_{2} }{I_{1} } = \frac{E_{v} ^{2} }{E_{h} ^{2} + E_{v} ^{2}}...............................(6)

But E_{h} = 2.3E_{v}......................(7)

Insert equation (7) into (6)

\frac{I_{2} }{I_{1} } = \frac{E_{v}^{2}  }{(2.3E_{v})^{2}   + E_{v} ^{2}   } \\\frac{I_{2} }{I_{1} } =  \frac{E_{v}^{2}  }{5.29E_{v}^{2}   + E_{v} ^{2}   }\\\frac{I_{2} }{I_{1} } =  \frac{E_{v}^{2}  }{6.29E_{v}^{2}  }\\\frac{I_{2} }{I_{1} } =\frac{1}{6.29} \\

\frac{I_{2} }{I_{1} }= 0.159

b) When the sunbather lies on his side, the vertical component vanishes, i.e E_{v} = 0

\frac{I_{2} }{I_{1} } = \frac{E_{h} ^{2} }{E_{h} ^{2} + E_{v} ^{2}}

\frac{I_{2} }{I_{1} } = \frac{(2.3E_{v} )^{2}  }{E_{v} ^{2} +(2.3E_{v} )^{2}}

\frac{I_{2} }{I_{1} } = \frac{5.29E_{v}^{2}  }{E_{v} ^{2} +5.29E_{v}^{2} }

\frac{I_{2} }{I_{1} } = \frac{5.29E_{v}^{2}  }{6.29E_{v}^{2} }\\\frac{I_{2} }{I_{1} } = \frac{5.29}{6.29} \\\frac{I_{2} }{I_{1} } = 0.84
