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
HELPPP WILL MARK BRAINLIST What type of image is formed by a lens if m= 2.7?
A. The image is smaller than the object and is virtual.
B. The image is smaller than the object and is real.
C. The image is larger than the object and is real.
D. The image is larger than the object and is virtual.
Answer:
the answer is C
Explanation:
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.
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.
