answer in the explanation!!

Explanation:

1: light being emitted from a light bulb is called electromagnetic waves ; transverse wave.

2: sound coming from a violin is a mechanical wave ; longitudinal wave.

3: a rock being dropped in a pond is a mechanical wave ; and im pretty sure its longitudinal and/or transverse.

Calculate the breadth B ( in degrees of 2θ ), due to the small crystal effect alone, of the powder pattern lines of particles of
Sloan [31]

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:  

\tau = \frac{K \lambda}{ B cos(\theta)}

<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>      

B = \frac{K \lambda}{ \tau cos(\theta)}

Now, factor B for the diameter of the particles (τ) is:

τ = 1000 Å:          

B = \frac{0.9 \cdot 1.5}{1000 \cdot cos(45)} = 1.91\cdot 10^{-3} rad = 0.109 ^{\circ}                

τ = 750 Å:

B = \frac{0.9 \cdot 1.5}{750 \cdot cos(45)} = 2.54\cdot 10^{-3} rad = 0.146 ^{\circ}

τ = 250 Å:

B = \frac{0.9 \cdot 1.5}{250 \cdot cos(45)} = 7.64\cdot 10^{-3} rad = 0.438 ^{\circ}

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

Θ = 10°:

B = \frac{0.9 \cdot 1.5}{250 \cdot cos(10)} = 5.48 \cdot 10^{-3} rad = 0.314 ^{\circ}

Θ = 45°:

B = 0.438°  

Θ = 80°:

B = \frac{0.9 \cdot 1.5}{250 \cdot cos(80)} = 0.031 rad = 1.78 ^{\circ}  

Have a nice day!

To determine the height of a flagpole, Abby throws a ball straight up and times it. She sees that the ball goes by the top of th
Kryger [21]

Answer:

H = 10.05 m

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

\Delta t = 4.1 - 0.5 = 3.6 s

now we have

\Delta t = \frac{2v}{g}

3.6 = \frac{2v}{9.8}

v = 17.64 m/s

so this is the speed at the top of flag pole

now we have

v_f - v_i = at

17.64 - v_i = (-9.8)(0.5)

v_i = 22.5 m/s

now the height of flag pole is given as

H = \frac{v_f + v_i}{2}t

H = \frac{22.5 + 17.64}{2} (0.5)

H = 10.05 m

Where is the kinetic energy and potential energy equal on a pendulum?
Alenkasestr [34]
-- 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.

What happens to the speed of an object when dropped at free fall
dedylja [7]

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.)
