<u>Answer:</u> The angle of diffraction is 0.498°
<u>Explanation:</u>
To calculate the angle of diffraction, we use the equation given by Bragg, which is:
where,
n = order of diffraction = 3
= wavelength of the light =
(Conversion factor:
)
d = spacing between the crystal planes = 0.100 mm = (Conversion factor: 1 m = 1000 mm)
= angle of diffraction = ?
Putting values in above equation:
Hence, the angle of diffraction is 0.498°
Answer:
Work done, W = 6 J
Explanation:
It is given that,
Force of gravity acting on the book, weight of the book is 15 N
We need to find the work done in lifting the book straight up for a distance of 0.4 meters.
The weight of the book is acting in downward direction and the book is lifted straight up, it means angle between them is 180 degrees. Work done is given by :
So, the magnitude of work done in lifting the book is 6 joules.
