Which of the following events may occur when IR radiation is absorbed?

Physics
1 answer:
Vilka [71]3 years ago
3 0

Answer:

c. More intense IR absorption occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.

Explanation:

When the molecules is exposed to the infrared radiation, the sample molecules absorb the radiation of wavelengths (specific to molecule) which causes change in the dipole moment of the sample molecules. The vibrational energy levels of the sample molecules consequently transfer from the ground state to the excited state.  

Frequency of absorption peak is determined by vibrational energy gap.

Intensity of absorption peaks is related to change of dipole moment and possibility of transition of the energy levels.  

Thus, by analyzing infrared spectrum,abundant structure information of the molecule can be known.

Hence, the correct answer to the question is

c. More intense IR absorption occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.

The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.

<h3>What is a magnetic field?</h3>

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

I is the current = 6.50 A

B is the magnetic field=f 2.71 X 10⁻⁵ T

The force on the wire is;

\rm F= BIL \\\\\ F=2.71 \times 10^{-5} \ T \times 6.50 \  A \times 1.50 \ m \\\\\ F=0.000264225 \ N

Hence, the force on one of the wires will be 0.000264 N.

A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvat
madam [21]

Answer:

12 cm

Explanation:

We shall use Lens makers formula here which is as follows

\frac{1}{F} =(\mu-1) (\frac{1}{R_1} -\frac{1}{R_2})

Put μ = 1.5 , R₁ = 10 cm ,R₂ = -  15 cm ( according to sign convention )

\frac{1}{F} =(1.5-1) (\frac{1}{10} -\frac{1}{-15})

= .5 x ( 15 + 10 ) / 15 x 10

= \frac{25}{2\times10\times15}

F = 12 cm

Consider a car engine running at constantspeed. That is, the crankshaft of the en-gine rotates at constant angular velocity whil
Irina-Kira [14]

Answer:

The value is  |v| = 7.39 \  m/s

Explanation:

From the question we are told that

    The angular speed is  w = 2030 \ rpm = \frac{2030 * 2 * \pi }{ 60} =  212.61 \ rad/s

    The distance between the minimum and maximum external position is  d = 6.95 \ cm  = 0.0695 \ m

Generally the amplitude of the crank shaft is mathematically represented as

         A =  \frac{d}{2}      

=>     A =  \frac{0.0695}{2}    

=>     A =  0.03475 \  m

Generally the maximum speed of the piston is mathematically represented as

        |v| = A * w  

=>    |v| = 0.03475 * 212.61

=>    |v| = 7.39 \  m/s

Correct the sentence below to reflect an “I” statement. 
Anarel [89]
The word “you” shouldn’t be used, and I learned the I statement to have your feelings stated, then when, then because, and finally a want. So, to correct this, an appropriate statement would be “ I feel misunderstood when I am treated like a child because my curfew is set for 9:00 pm on the weekends and I want to be seen as your equal and as though you are not superior to me. You can use the word “you” after stating you want something out of the other person.

one car moving in a straight line covers one third distance in 20km/h and rest in 60km/h . find the average speed
Fynjy0 [20]

Answer:

36 km/h

Explanation:

If d is the total distance, then the time spent driving at 20 km/h is:

t₁ = (d/3) / 20

t₁ = d / 60

And the time spent driving at 60 km/h is:

t₂ = (2d/3) / 60

t₂ = d / 90

So the total time is:

t = t₁ + t₂

t = d/60 + d/90

t = d/36

The average speed is the total distance divided by total time:

s = d / t

s = d / (d/36)

s = 36

The average speed is 36 km/h.
