Answer: The Electrostatic force of attraction or repulsion between two charges shows that the Newton's third law applies to electrostatic forces.

Explanation: Consider two Oppositely charged charges separated by distance d.

The electrostatic force exerted by charge 1 on charge 2 is.

By Coulomb's Law :

               F1  = k \frac{Q1 Q2}{d2}.....................................(1)

The electrostatic force exerted by charge 2 on charge 1 is.

              F2  = - k \frac{Q1 Q2}{d2} ................................. (2)

negative sign shows that force are in opposite direction.

 

From Equation 1 and 2

              F1 = - F2

Which implies Newton Third law.

Place the following types of electromagnetic radiation in order of increasing wavelength. ultraviolet light gamma rays radio wav
kvv77 [185]

Answer: gamma rays < ultraviolet light < radio waves

Explanation: We have to explain the ordering we take into account a relationship for electromagnetic wave, which is given by:

c=λ*ν c is the speed of light.  λ and ν are the wavelegth and the frequency of the waves.

Then we also know that the high frequency of these radiation correspond to the gamma ray (10^18 1/s) while the lowest correspond to radio wave (10^8 1/s) so:

The ultraviolet ligth is ranged at frequencies of 10^16 1/s located bewteen gamma and radio radiation.

as large frequency lower wavelength we can order these radiations from short to long wavelengths as follows:

gamma rays < ultraviolet light < radio waves
