Answer:
For differents τ:
τ = 1000 Å → B = 0.11°
τ = 750 Å → B = 0.15°
τ = 250 Å → B = 0.44°
For differents Θ:
Θ = 10° → B = 0.31°
Θ = 45° → B = 0.44°
Θ = 80° → B = 1.78°
Explanation:
To factor B is related to the size of particles, Θ, and λ by the Scherrer equation:

<em>where τ: size of the particles, λ: is the wavelenght of the X-Rays, B: is the line broadening at half the maximum intensity, Θ: angle of incidence and K: is a shape factor with typical value of 0.9 </em>

Now, factor B for the diameter of the particles (τ) is:
τ = 1000 Å:
τ = 750 Å:

τ = 250 Å:
For τ = 250 Å, factor B for angles of incidence is:
Θ = 10°:

Θ = 45°:
B = 0.438°
Θ = 80°:
Have a nice day!
Answer:

Explanation:
If the stone will reach the top position of flag pole at t = 0.5 s and t = 4.1 s
so here the total time of the motion above the top point of pole is given as

now we have



so this is the speed at the top of flag pole
now we have



now the height of flag pole is given as



-- ends of the swing . . . . . all potential energy, no kinetic
-- middle of the swing . . . . all kinetic energy, no potential
-- Potential energy and kinetic energy are equal at the points
(one on each side of the swing) where the bob is at a height
that is midway between the height at the end of the swing and
the height at the bottom of the swing.
If it's not falling through air, water, smoke, or anything else,
and gravity is the only force on it, then its speed increases
at a constant rate ... 9.8 meters per second for every second
it falls. (That's the number on Earth. It's different in other places.)
