Calculate the minimum wavelength (λ0) for the continuous spectrum of X-rays emitted when.. a) 30-kV electrons strike a cobalt (C

Sholpan [36]

Explanation:

The relationship between the wavelength and the potential difference V is given by :

$\lambda=\dfrac{h}{\sqrt{2me}}\times \dfrac{1}{\sqrt{V}}$

Putting the values of known parameters,

$\lambda=\dfrac{12.28}{\sqrt{V} }\times 10^{-10}\ m$

(a) $V=30\ kV=30000\ V$

$\lambda=\dfrac{12.28}{\sqrt{30000} }\times 10^{-10}\ m$

$\lambda=7.08\times 10^{-12}\ m$

(b) $V=60\ kV=60000\ V$

$\lambda=\dfrac{12.28}{\sqrt{60000} }\times 10^{-10}\ m$

$\lambda=5.01\times 10^{-12}\ m$

Hence, this is the required solution.

Suppose that video game discs are a normal good. If the income of video game players increases, you predict that in the market

DENIUS [597]

Answer:

Both equilibrium price and quantity will increase.

Explanation:

An increase in the income of video game players will surely lead to an upward shift in the supply and demand curve. This shift in the supply and demand curve would affect the equilibrium price and quantity positively leading to a correspondent increase in the equilibrium price and quantity.

Marie curie was a scientist who won two nobel prizes in the early 1900s for her work with.

Arada [10]

She remains the only person to be honored for accomplishments in two separate sciences. Curie received the Nobel Prize in Physics in 1903, <u>along with her husband and Henri Becquerel, </u>for their work on radioactivity.

<h3>What did Marie Curie discover?</h3>

Relentless regardless of a vocation of truly requesting and at last lethal work, she found polonium and radium, supported the utilization of radiation in medication and essentially changed how we might interpret radioactivity. Curie was conceived Marya Skłodowska in 1867 in Warsaw.

Curie was the first person to win two Nobel Prizes.
She managed it all without a fancy lab.
Nobel Prizes were a family affair.
Curie was the first female professor at Sorbonne University.
Curie is buried in the Panthéon in Paris.

Suppose a plot of inverse wavelength vs frequency has slope equal to 0.119, what is the speed of sound traveling in the tube to

strojnjashka [21]

Answer:

8.40 m/s

Explanation:

Slope of the plot is 0.119

Slope of a plot is given by the change in y direction divided by the change in x direction

Here, the y axis represents inverse wavelength and the x axis represents frequency.

f = Frequency (Hz, assumed)

v = Phase velocity (m/s, assumed)

λ = Wavelength (m, assumed)

So, slope

$m=\frac{\frac{1}{\lambda}}{f}$

Now,

$\lambda=\frac{v}{f}\\\Rightarrow \lambda^{-1}=\frac{f}{v}$

$\\\Rightarrow m=\frac{\frac{f}{v}}{f}\\\Rightarrow 0.119=\frac{1}{v}\\\Rightarrow v=\frac{1}{0.119}\\\Rightarrow v=8.40\ m/s$

The speed of sound travelling in the tube is 8.40 m/s
