Answer:
t = 1.09 s.
Explanation:
This is a one-dimensional kinematics question, so the equations of kinematics will be sufficient to solve the question.
This quadratic equation can be solved using determinant.
Of course, we will choose the positive time.
Answer: The electron number density (the number of electrons per unit volume) in the wire is .
Explanation:
Given: Current = 5.0 A
Area =
Density = 2.7 , Molar mass = 27 g
The electron density is calculated as follows.
where,
= density
M = molar mass
= Avogadro's number
Substitute the values into above formula as follows.
Thus, we can conclude that the electron number density (the number of electrons per unit volume) in the wire is .
