Explanation:

The name semiconductors makes perfect sense because not all substances conducts electricity readily. Some substances have to fulfill certain conditions for electric current to pass through them. They are called semi-conductors.

A conductor is a substance that allows the passage of electricity through it. They are usually metallic solids.
A non-conductor usually called insulators do not allow electric currents to go through them.
The presence of free mobile electrons in an body allows for electric conductance.
Silicon is a popular semi-conductor.
To accommodate substances whose conductance lies between those of conductors and non-conductors, the term semi-conductor is best to use.

How does flowing water change the earths surface

Art [367]

Deposition occurs when gravity's downward pull on sediment is greater than the push of flowing water or wind. Rivers and streams erode soil, rock, and sediment. Sediment is tiny grains of broken-down rock.

An RL series circuit is connected to an ac generator with a maximum emf of 20 V. If the maximum potential difference across the

Rama09 [41]

If the maximum emf of the ac generator is 20 V and the maximum potential difference across the resistor is 16 V Then the maximum potential difference across the inductor is 4 V.

Calculation:

Step-1:

It is given that the RL circuit is connected to a 20 V ac generator. The maximum potential difference across the resistor is 16 V. It is required to find the maximum potential drop across the inductor.

Step-2:

The maximum emf of the generator is equal to the sum of the maximum potential difference across the resistor and the maximum potential difference across the inductor.

Therefore,

The maximum potential difference across the inductor + Maximum maximum potential difference across the resistor = Maximum emf of the generator

Thus,

Maximum maximum potential difference across the inductor + 16 V = 20 V

Therefore,

Maximum maximum potential difference across the inductor = 20 V - 16 V = 4 V

N76 [4]

Answer: The total momentum before the docking maneuver is $mV_{1}+MV_{2}$ and after the docking maneuver is $(m+M) U$

Explanation:

Linear momentum $p$ (generally just called momentum) is defined as mass in motion and is given by the following equation:

$p=m.v$

Where $m$ is the mass of the object and $v$ its velocity.

According to the conservation of momentum law:

"If two objects or bodies are in a closed system and both collide, the total momentum of these two objects before the collision $p_{i}$ will be the same as the total momentum of these same two objects after the collision $p_{f}$ ".
