You have to have electrons that are in the materials conduction band. Then you apply a voltage across the material.
Answer:
Zero
Explanation:
The work done on an object is given by:
where
F is the force applied on the object
d is the displacement of the object
is the angle between the direction of the force and the displacement
In this problem, you are pushing again a stationary wall: this means that the walls does not move. As a result, the displacement is zero: d=0. Therefore, the work done is also zero: W=0.
Answer: it is incorrect because skepticism helps scientists recognize when ideas are not supported by evidence.
Explanation:
Skepticism is simply the understanding that there can be uncertainty when it comes to knowledge in certain areas.
From the question, we are informed that John doesn't think that skepticism should play an important role in the scientific process and that he says that skepticism interferes with scientific consensus.
The statement that best describes John's conclusion is that it is incorrect because skepticism helps scientists recognize when ideas are not supported by evidence.
The angle between the two vectors is 0⁰, thus the two vectors are parallel to each other.
<h3>Angle between the vectors</h3>
The angle between the vectors describes the direction of the vector and the value of the angle can be determined from the horizontal and vertical components of the vectors as shown below.
The sum of the horizontal components and vertical components of the vectors is calculated as follows;
Sum of the horizontal component of the vectors, x = 1 + 1 = 2
Sum of the vertical component of the vectors, y = -1 + 1 = 0
The angle between the vectors is calculated as follows;
θ = arc tan (y/x)
θ = arc tan (0/2)
θ = arc tan (0)
θ = 0⁰
The angle between the two vectors is 0⁰, thus the two vectors are parallel to each other.
