  • initial velocity=u=0m/s
  • Final velocity=60km/h=v

Convert to m/s

\\ \Large\sf\longmapsto v=60\times \dfrac{5}{18}=16.6m/s

  • Time=t=5min=5×60=300s

We know

\boxed{\Large{\sf Acceleration=\dfrac{v-u}{t}}}

\\ \Large\sf\longmapsto Acceleration=\dfrac{16.6-0}{300}

\\ \Large\sf\longmapsto Acceleration=\dfrac{16.6}{300}

\\ \Large\sf\longmapsto Acceleration=0.05m/s^2

  • Distance=s

Using second equation of kinematics

\boxed{\Large{\sf s=ut+\dfrac{1}{2}at^2}}

\\ \Large\sf\longmapsto s=0(300)+\dfrac{1}{2}(0.05)(300)^2

\\ \Large\sf\longmapsto s=0.05\times 150^2

\\ \Large\sf\longmapsto s=0.05\times 22500

\\ \Large\sf\longmapsto s=1125m

I NEED HELP PLEASE, THANKS! :)

Answer:

Radio waves have a wavelength between 10^{-9}m and 10^{-12}m

While,

X rays have a wavelength between 1m and 10km.

=> It is one of the condition of diffraction that the obstacle (coming in the way) must be comparable with the size of the wavelength.

=> This shows, that radio waves have a wavelength which is comparable with the size of buildings and can really easily diffract through it

=> While, X-rays are big enough to diffract through the wall.

So, if an X-ray technician stands behind a wall during the use of her machine, she will remain safe.
