Plz help An X-ray technician will place a lead cloth over parts of your body when taking an X-ray to protect your cells from bei
ng damaged. Why do X-rays have the potential to harm your body but radio waves do not?
Question 6 options:
a.X-rays have a taller wavelength than radio waves as shown in the diagram, so they are more harmful.
c.Radio waves have longer wavelengths than X-rays and therefore carry more energy than X-rays.
c.Radio waves are shorter than X-rays and therefore weaker in strength..
d.X-rays have a much shorter wavelength than radio waves, and therefore carry more energy that can be transferred to your body.

Answer:
λ = 5.656 x 10⁻⁷ m = 565.6 nm
Explanation:
Using the formula of fringe spacing from the Young's Double Slit experiment, which is given as follows:
where,
λ = wavelength = ?
Δx = fringe spacing = 1.6 cm = 0.016 m
L = Distance between slits and screen = 4.95 m
d = slit separation = 0.175 mm = 0.000175 m
Therefore,
<u>λ = 5.656 x 10⁻⁷ m = 565.6 nm</u>
Answer:
Explanation:
Calculating the exit temperature for K = 1.4
The value of is determined via the expression:
where ;
R = universal gas constant =
k = constant = 1.4
The derived expression from mass and energy rate balances reduce for the isothermal process of ideal gas is :
------ equation(1)
we can rewrite the above equation as :
where:
Thus, the exit temperature = 402.36 K
The exit pressure is determined by using the relation:
Therefore, the exit pressure is 17.79 bar
