When an electron is displaced in a semiconductor, the hole that's left behind isA. attracted to the negative terminal of the voltage source.
B. attracted to the anode of the voltage source.
C. considered an impurity in the crystal.
D. incapable of carrying a charge.

(D. is wrong)

Answers

answer is A : attracted to the negative terminal of the voltage source
 I think, that the "hole"moves as it captures a free electron leaving another hole in a slightly different place. The electron leaving leaves a net + charge, which is attracted to the negative terminal. Because the "hole" behaves as a positive charge it is attracted towards the negative terminal.

Answer:

A. attracted to the negative terminal of the voltage source.

Explanation:

bc that is what the hole that's left behind does

Electrons always fill orbitals in the same order. Each s orbital holds 2 electrons, each set of p orbitals holds 6 electrons, each set of d orbitals holds 10 electrons, and each set of f orbitals holds 14 electrons. The order in which orbitals are filled, from first to last, is: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p

Only powerful X-rays can be used.
Only beta particles can be used.
Only alpha particles can be used.

Answers

The statement that is true about the use of radiation to treat cancer is that only powerful X-rays can be used. The radiation used for cancer treatment is known as ionizing radiation. These forms ions in the cells which could kill or stop them from growing. This type of radiation is have more energy than radio waves, microwaves and visible light.

Answer:

Only powerful x-rays can be used
