In semiconductors, you can change how easily electrons move through them. That is option 2.
<h3>What are semiconductors?</h3><h3 />
Semiconductors is defined as those substances that possess the characteristics of both metal and non metal.
Examples of semiconductors include the silicon, germanium, and gallium arsenide elements.
The semiconductors are able to conduct electricity through the presence of electrons and holes in them.
The movement of these electrons can be controlled through the addition of impurities to the semiconductor material.
Therefore, in semiconductors, you can change how easily electrons move through them.

The tension in the cable is 169.43 N and the vertical component of the force exerted by the hi.nge on the beam is 114.77 N.
<h3>Tension in the cable</h3>
Apply the principle of moment and calculate the tension in the cable;
Clockwise torque = TL sinθ
Anticlockwise torque = ¹/₂WL
TL sinθ = ¹/₂WL
T sinθ = ¹/₂W
T = (W)/(2 sinθ)
T = (29 x 9.8)/(2 x sin57)
T = 169.43 N
<h3>Vertical component of the force</h3>
T + F = W
F = W - T
F = (9.8 x 29) - 169.43
F = 114.77 N
Thus, the tension in the cable is 169.43 N and the vertical component of the force exerted by the hi.nge on the beam is 114.77 N.

The type of bond that is found between the atoms of a molecule is called "COVALENT" bond.
A covalent bond is where two atoms share a pair of electrons.
