Ilya [14]4 years ago
7 0

Answer:

Diffraction is when the light takes place if the size is obstacle

Explanation:

Diffraction of light takes place if the size of obstacle is comparable to the wavelength of light. Light waves are very small in wavelength. If the size of opening or obstacle is near to this limit, only then we can observe the phenomenon of diffraction

a 0.0818 kg salt shaker on a rotating table feels an inward frictional force of 0.108 N when it is moving 0.333m/s. what is the
serg [7]

<u>Answer:</u>

<em>The required radius of its motion is 0.084m.</em>

<u>Explanation:</u>

The formula for calculating the required  radius of its motion is given by

F = (mv^2)/r

Where <em>m= mass  </em>

<em>V= moving velocity </em>

<em>F=frictional force </em>

<em>r = radius of its motion </em>

Then the required radius of its motion is given by

r =(mv^2)/F

<u>Given that </u>

<em>mas =0.0818 kg </em>

<em>Frictional force= 0.108 N </em>

<em>Moving with Velocity of  = 0.333 m/s </em>

<em>radius of its motion = \frac{[0.0818 kg \times (0.333 m/s)^2]}{0.108 N}</em>

<em>Hence the required radius of its motion is r = 8.4 cm=0.084m</em>
