Answer:
The wavelength of monochromatic light is - <u>725nm</u>
Explanation:
Lets calculate -
<u>Given -</u> The dark fringes are 2.0mm wide and the glass plate is 16.0cm
Thus , the number of fringes is -
Here , converting the units into metre
=
= 80
Now , the expression used here is -
Putting the given values,
=725nm
<u>Therefore , the answer is 725nm . </u>
I would say Book B.
Gravitational Potential Energy is mass * gravity * height.
Gravity is same for the same, it's constant.
Book C is the lowest, so it has less height.
And Book B is clearly the more massive of Book A and Book B, which are the same height.
Book B
Answer:
748.8 kJ
Explanation:
Kinetic energy is given by
where m is the mass of the body, v is the velocity
Substituting 2600 Kg for m and 24 m/s for velocity
Therefore, kinetic energy is 748.8 kJ
Answer: degrees divided by 360
