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:

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

If at a particular instant and at a certain point in space the electric field is in the x-direction and has a magnitude of 5.00 V/mV/m, what is the magnitude of the magnetic field of the wave at this same point in space and instant in time

Answers

Answer:

the magnitude of the magnetic field of the wave is 16.7 nT

Explanation:

Given the data in the question;

Electric field E = 5.00 V/m

we know that the expression for the electric field of an electromagnetic wave in terms if magnetic field is;

E = cB

where c is the speed of light ( 3 × 10⁸ m/s )

and B is the magnetic field

so we solve for the magnetic field

B = E / c

we substitute in the value of E and c

B = (5.00 V/m) / (3 × 10⁸ m/s)

B = 1.67 × 10⁻⁸ T

B = 1.67 × 10⁻⁸ T [tex]( \frac{1nT}{10^{-9}T} )[/tex]

B = 16.7 nT

Therefore, the magnitude of the magnetic field of the wave is 16.7 nT

So, the formed image will be real and inverted.

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.
