<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:
a. one-half as great
Explanation:
The power developed by the first lifter is one-half as great as that of the second person.
Power is defined as the rate at which work is done;
Power =
Since the two lifters do the same work at different time, let us estimate their power;
P₁ = P₂ =
We see that for P₁, power is half of the work done whereas in P₂ power is the same as the work done.
Therefore,
The power of the first weight lifter is one-half the second lifter.
