Answer:
12
Explanation:
What is the total kinetic energy of a hoop of radius 1 m and mass 2 kg that rolls at an
angular velocity of 1 rad/s?
Answer:
Explanation:
Using Snell's law which is represented by
Making 
the subject of the formula then
Here 
and are the angles of incidence and refraction in water and air respectively
and 
are refraction index
Substituting 1.0003 for and 1.33 for then 
for 
we obtain
Answer : Infrared rays have a shorter wavelength than radio waves.
Explanation :
The wavelength of Infrared rays is 700 nm – 1 mm
The wavelength of X- rays is 0.01 nm – 10 nm
The wavelength of UV rays is 10 nm – 400 nm
The wavelength of radio waves is 1 meter – 100,000 km
The wavelength of gamma rays is less than 0.01 nm
So, from the above data it is clear that the wavelength of the infrared rays have a wavelength shorter than the radio waves.
Hence, the correct option is (C) " radio waves ".
<span>The wave oscillates in a single plane.Polarization of light is the process of transforming the unpolarized light into a polarized light in which the polarized light waves vibrates in a single plane by using reflection, refraction, and passing through nicol prism and tourmaline glass.
