A material that provides little or no resistance to the flow of electric current is called a(an) A. circuit / B. conductor / C. insulator / D. resistor.
Answers
The correct answer is B) Conductor
A conductor is a material that allows for the flow of electrical charge (electrical current). This type of material provides little or no resistance to the flow of electric current. This is due to the fact that these type of materials have free electrons which conduct the flow of electrical current in any direction.
Different types of conductors have different resistances. Some types of materials are good conductors whereas some are not so good.
Some common conductors are Copper, gold, silver and aluminium.
An insulator is the an object of type of material which have a strong resistance to the flow of electric current. Some common insulators are glass, wood and plastic.

Answer:
The other person who answered is incorrect- the real answer is light.
Explanation:
A mechanical wave is a wave that requires a medium. A medium is any substance that has a defined set of physical properties and can transmit energy. A medium can be a solid, liquid, or gas. Some examples of a medium include an iron bar, the ground, water, lava, air, and helium in a balloon.
The answer is not sound because sound travels through waves through the air. If you were to put a source of sound in a container that contains no air, you would not be able to hear the sound through the container. Since sound has a wave and a medium, it is a mechanical wave.
The answer is not waves in the ocean because, obviously, this is a wave. Its medium is the water. Since it has a wave and a medium, it is a mechanical wave.
The answer is not waves in a wheat field because, again, this is a wave. The medium is the air. Since it has a wave and a medium, it is a mechanical wave.
The answer is light. Light travels through electromagnetic waves. However, it does not require a medium. Light can travel not only through air and solid materials, but also through the vacuum of space. Since light does not require a medium, it is not a mechanical wave.

You see if the skier is going 250 meters a second 250 times 10 is 2500 so it would take the skier 10 seconds.
Answer:
10 sec.
Explanation:
distance = 2500 meters
velocity = 250 meter/second
time = distance / velocity
= 2500 meters
250 meter/second
= 10 sec.

It will take a car, 2.59 s to accelerate from 15.2 to 23.5 m/s.
What is Speed?
speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, the car has an average acceleration of 3.2 m/s².
To solve this problem, we can use the following kinematic equation:
v = u +at
where:
v is the final velocity (23.5 m/s)
u is the initial velocity (15.2 m/s)
a is the acceleration (3.2 m/s^2)
t is the time
We can rearrange this equation to solve for t:
t = (v -u)/a
substituting the values we have:
t = (23.5 - 15.2 ) / 3.2
t = 2.59375 seconds
Therefore, it will take approximately 2.59 seconds for the car to accelerate from 15.2 m/s to 23.5 m/s with an average acceleration of 3.2 m/s².

Hello!
How long will it take a car to accelerate from 15.2 m/s to 23.5 m/s if the car has an average acceleration of 3.2 m/s² ?
We have the following data:
Vf (final velocity) = 23.5 m/s
Vi (initial velocity) = 15.2 m/s
ΔV (speed interval) = Vf - Vi → ΔV = 23.5 - 15.2 → ΔV = 8.3 m/s
ΔT (time interval) = ? (in s)
a (average acceleration) = 3.2 m/s²
Formula:
Solving:
Answer:
The car will take approximately 2.6 seconds to accelerate
