A sodium vapor lamp operates by using electricity to excite the highest-energy electron to the next highest-energy level. light

viva [34]

Answer:

The energy levels are: 3s and 3p

Explanation:

The sodium (Na) element, with atomic number 11 (number of protons: Z=11), has the next electronic configuration:

Z=11: 1s² 2s² 2p⁶ 3s¹ = [Ne] 3s¹

Hence, the electricity used in a sodium vapor lamp will excite the electron of the energy state n=3 from the s-orbital to the next highest energy p-orbital which then drops back to the lower energy s-orbital by the emission of a photon resulting in the production of light.

The transition of the electron is:

Excitation: [Ne] 3s¹ → [Ne] 3s⁰ 3p¹

Emission: [Ne] 3p¹ → [Ne] 3s¹

So, the energy levels that are involved in the process are 3s and 3p.

Have a nice day!

An object travels at constant velocity of 3 m/s for a time period of 7.15 s. What is its displacement over this time?

son4ous [18]

Hi there!

We can use the following equation for constant velocity:

$\large\boxed{d = vt}$

d = displacement (m)

v = velocity (m/s)

t = time (s)

Plug in the givens:

$d = 3 * 7.15 = \boxed{21.45 m}$

Two loudspeakers, 4.5 m apart and facing each other, play identical sounds of the same frequency. You stand halfway between them

irga5000 [103]

Answer:

A) Frequency of Sound B = 242.85 Hz

B) Frequency at maximum sound intensity = 485.71 Hz

Explanation:

From intensity and path difference equations of sound waves;

the path difference for maximum intensity is x = nλ

Now, for minimum intensity, the path difference(x) is given as;

x = (2n - 1)(λ/2)

Since he has moved 0.35m,the total Path difference = (0.35) + (0.35) = 0.7 m

As n = 1,

0.7 = =(2(1) - 1)(λ/2)

So, (λ/2) = 0.7

And thus λ = 0.7 x 2 = 1.4m

From wavelength equation, we know that; λ = v/f and f = v/λ

Where v is velocity of sound

Thus ; frequency(min) = 340/1.4= 242.85 Hz

B) Now for max the path difference;

From earlier said, x = nλ

So at n=1 and λ = 0.7

x = 1 x 0.7 = 0.7

So following same equation for frequency, fmax = 340/0.7 = 485.71 Hz

Why the circulatory system of a grasshopper does not need to carry gases to and from the grasshopper cells

son4ous [18]

Answer:

Explanation:

In vertebrates, the circulatory system is responsible for transporting oxygen to all the tissues and removing carbon dioxide from them. ... In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process.
