X- rays with a wavelgnth of 0.0700 nm diffract from a crystal. Two adjacne angels of x-ray diffraciton are 45.6 and 21.0 degrees
zhenek [66]

Answer:

0.15 nm

Explanation:

d = Distance between the atomic planes

m = Order

\theta_{m} = First angle = 45.6^{\circ}

\theta_{m+1} = Adjacent angle = 21^{\circ}

\lambda = Wavelength = 0.07 nm

From Bragg's relation we know

2d\cos\theta_{m}=m\lambda

2d\cos45.6^{\circ}=m0.07

2d\cos\theta_{m+1}=(m+1)\lambda

2d\cos21^{\circ}=(m+1)0.07\\\Rightarrow 2d\cos21^{\circ}=m(0.07)+0.07

So

2d\cos21^{\circ}=2d\cos45.6^{\circ}+0.07\\\Rightarrow 2d(\cos21^{\circ}-\cos45.6^{\circ})=0.07\\\Rightarrow d=\dfrac{0.07}{2(\cos21^{\circ}-\cos45.6^{\circ})}\\\Rightarrow d=0.14962\ \text{nm}

The distance between the atomic planes is 0.15 nm.

One source error is __________, and one of its solutions is having a lie scale inserted into the assessment. A. social desirabil
8090 [49]

The correct answer is B; Deliberate deception

Further Explanation:

Deception is one when a person is fully aware of what they are doing. They are hiding the truth and making a conscious decision to tell someone something that has no truth. Deception can also be used when describing a magic trick such as a sleight of hand.

Lie scales are used when there are redundant questions that ask the same questions over and over with different formats to see if the answers are consistent over time.

A cricket player hit a ball of mass 250 g moving with velocity of 6 m/sec. if ball move with a velocity of 9 m/sec in opposite d
PolarNik [594]

Explanation:

Given that,

Mass of a ball, m = 250 g = 0.25 kg

Initial velocity of the ball, u = 6 m/s

Final velocity of the ball, v = -9 m/s

(a) Impulse of the system is given by :

Impulse = change in momentum

J = m(v-u)

J = 0.25(-9-6)

= -3.75 kg-m/s

(b) Impulse = Ft

If t = 0.5 min = 30 s

So,

F=\dfrac{J}{t}\\\\F=\dfrac{-3.75}{30}\\\\F=-0.125\ N

So, impulse of the system is -3.75 kg-m/s and the force is -0.125 N.
