Find the magnitude of the torque that acts on the molecule when it is immersed in a uniform electric field of 6.19×105 N/C with
Ivan

Answer:

\tau=5.81\times 10^5p\ N-m

Explanation:

We have,

Electric field, E=6.19\times 10^5\ N/C

The electric dipole vector at an angle of 69.9 degrees from the direction of the field.

The torque acting on a molecule is given by :

\tau=p\times E\\\\\tau=pE\sin\theta

p is electric dipole moment

\tau=p\times 6.19\times 10^{5}\times \sin (69.9)\\\\\tau=5.81\times 10^5p\ N-m

So, the magnitude of the torque acting on the molecule is 5.81\times 10^5p\ N-m.

The ____ of emitted light depends directly on the energy between the two orbits and this determines the color of the light
Anna007 [38]

The <u>frequency</u> of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.

<h3>What is light?</h3>

Light can be defined as a form of electromagnetic waves that does not require any medium for its propagation. This ultimately implies that, light is a form of wave that is generally referred to as a visual signal because it can be seen with the eyes.

According to the model of light wave, the <u>frequency</u> of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.

<em>In conlcusion, the </em><u><em>frequency</em></u><em> of emitted </em><em>light</em><em> is highly dependent on the </em><em>energy</em><em> between the two (2) </em><em>orbits</em><em>.</em>
