A p-n junction diode is, as the name suggests, an electronic device that is made up of a p-type semiconductor and an n-type semiconductor joined together.

a. True
b. False

Answers

Answer 1

Answer:

a. True

Explanation:

When a p-type semiconductor is placed adjacent to an n-type semiconductor  the common plane thus formed is termed as P-N Junction or  P-N Junction Diode.

The diode is formed by melting both p-type and n-type semiconductors through a special manufacturing process called "Thermo-Compression Proces".

The P-N junction has a property of one-way conduction. It means it only allows the current to pass through it in one direction and the current flow is practically zero in the other direction. Thus, it can act as a diode. The p-side acts as the anode, while the n-side acts as the cathode.

Hence, the correct option is:

a. True

A certain object is subject to two forces: a 10-N force straight up and a 10-N force straight down. A student states that since both forces are in the vertical direction, the object cannot be moving horizontally. Why is this an incorrect conclusion?

A.
The vertical forces are balanced.
B.
Vertical net forces can cause horizontal motion.
C.
A horizontal force is not required for horizontal movement.
D.
Two vertical forces can combine to form a horizontal resultant force.

Answers

Answer:

C. Consider projectile motion. If an object starts out at some angle and only vertical forces (gravity) are present, the horizontal speed remains constant thruout the motion.
