Answer:

$5.1645\times 10^{-11}\ m$

Explanation:

n = Order = 1

c = Speed of light = $3\times 10^8\ m/s$

f = Frequency = $3\times 10^{18}\ Hz$

$\theta$ = Angle = $75.5^{\circ}$

Lattice spacing is given by

$d=\dfrac{n\lambda}{2\sin\theta}\\\Rightarrow d=\dfrac{n\times c}{f2\sin\theta}\\\Rightarrow d=\dfrac{1\times 3\times 10^{8}}{3\times 10^{18}\times 2\times \sin75.5^{\circ}}\\\Rightarrow d=5.1645\times 10^{-11}\ m$

The lattice spacing of the crystal is $5.1645\times 10^{-11}\ m$

A 4810 kg demolition ball swings at the end of a 12.3 m cable on the arc of a vertical circle. At the lowest point of the swing,

faust18 [17]

The tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.

<h3>Tension in the cable</h3>

The tension in the cable supporting the swing of the ball is calculated as follows;

T = mg + mac

T = mg + m(v²)/r

T = (4810 x 9.8) + (4810 x 1.06²)/12.3

T = 47,577.4 N

Thus, the tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.
