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:
T = 6.0 N
Explanation:
given,
mass of the cord = 0.46 Kg
length of the supports = 7.2 m
time taken to travel = 0.74 s
tension in the chord = ?
using formula for tension calculation
v = 9.73 m/s
now, calculation of tension
T = 6.0 N
The tension in the cord is equal to 6.0 N.
