Answer:
The current density is
The drift velocity is
Explanation:
From the question we are told that
The nominal diameter of the wire is
The current carried by the wire is
The power rating of the lamp is
The density of electron is
The current density is mathematically represented as
Where A is the area which is mathematically evaluated as
Substituting values
So
The drift velocity is mathematically represented as
Where e is the charge on one electron which has a value
So
Answer:
h (3) = 0
Explanation:
In this exercise they give us the expression that governs the movement
h (t) = 5 sin (2πt)
remember that the angles are in radians.
To calculate the instantaneous velocity we substitute
h (3) = 5 sin (2π 3)
h (3) = 0
therefore the body this is its position of equilibrium
Iron and nickel are the elements most similar to cobalt
I got B,when you subtract 3/5 from NEGATIVE 2/3 it creates a negative 19 over a positive 15.
