Using planck's constant and a wavelength of 656e-9 what is the energy of the photon

lbvjy [14]

Answer:

3.03e-19 J

Explanation:

Use the formula E = hc/λ

Where:

h (Planck's constant) = 6.626e-34 J*s

c (speed of light, constant) = 3.00e8 m/s

λ (wavelength) = 656e-9 m

E = energy (in Joules)

E = (6.626e-34 * 3.00e8) / 656e-9 = 3.03018293e-19 = 3.03e-19 J

What are the first three overtones of a bassoon that has a fundamental frequency of 90.0 Hz? It is open at both ends. (The overt

vekshin1

Answer:

$f_{2}=180Hz,f_{3}=270Hz,f_{4}=360Hz\\$

Explanation:

Given data

Frequency f=90 Hz

To find

First three overtones of bassoon

Solution

The fundamental frequency of bassoon is found by substituting n=1 in below equation

f=v/λ=nv/2L

$f_{1}=v/2L$

The first overtone of bassoon is found by substituting n=2

$f_{2}=2v/2L\\f_{2}=2(v/2L)\\as \\f_{1}=v/2L\\So\\f_{2}=2f_{1}\\f_{2}=2(90Hz)\\f_{2}=180Hz$

The second overtone of bassoon is found by substituting n=3

$f_{3}=3v/2L\\f_{3}=3(v/2L)\\as \\f_{1}=v/2L\\So\\f_{3}=3f_{1}\\f_{3}=3(90Hz)\\f_{3}=270Hz$

The third overtone of bassoon is found by substituting n=4

$f_{4}=4v/2L\\f_{4}=4(v/2L)\\as \\f_{1}=v/2L\\So\\f_{4}=4f_{1}\\f_{4}=4(90Hz)\\f_{4}=360Hz$

an ice Puck travels 18 m in 3 S before it slides into the goal what is the speed of the traveling puck

DiKsa [7]

Answer:

$\boxed {\boxed {\sf 6 \ meters \ per \ second}}$

Explanation:

Speed can be found by dividing the distance by the time.

$s=\frac{d}{t}$

The distance is 18 meters and the time is 3 seconds.

$d= 18 \ m \\t= 3 \ s\\$

Substitute the values into the formula.

$s=\frac{18 \ m }{ 3 \ s }$

Divide.

$s= 6 \ m/s$

The speed of the puck is <u>6 meters per second.</u>
