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:
The object accelerates downward at 4 m/s² since the tension on the rope is less than weight of the object.
Explanation:
Given;
mass of the object, m = 2 kg
weigh of the object, W = 20 N
tension on the rope, T = 12 N
The acceleration of the object is calculated by applying Newton's second law of motion as follows;
T = F + W
T = ma + W
ma = T - W
(the negative sign indicates deceleration of the object)
The object accelerates downward at 4 m/s² since the tension on the rope is less than weight of the object.
The distance between two successive troughs or crests is known as the wavelength. The wavelength of the light will be 1000 nm.
How do you define wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
Diffraction angle= 30⁰
Diffraction grating per mm= 250
wavelength = ?
Mathematically the equation of bright band is given by
m
Hence the wavelength of the light will be 1000 nm.
