The position compared to that of home is a reference to displacement, I believe.
Displacement = x total - x initial
So I believe the answer is 5 blocks due north (if you’re walking linearly from your home), unless the questions is referring to relative displacement, in which then you’d need to use the Pythagorean theorem to find the hypotenuse between both positions. And then you’d have to find theta for the degrees between the south direction and the other unmentioned direction. But I don’t think that’s the case.
Distance refers to x total and doesn’t care for direction, as this refers to a scalar quantity opposed to a vector. Thus the equation is just
d = x
So 8 blocks + 3 blocks = a distance of eleven blocks walked total
Answer:
162500000.
Explanation:
Given that
Diameter of the wire , d= 1.8 mm
The length of the wire ,L = 15 cm
Current ,I = 260 m A
The charge on the electron ,e= 1.6 x 10⁻¹⁹ C
We know that Current I is given as
![I=\dfrac{q}{t}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7Bq%7D%7Bt%7D)
I=Current
q=Charge
t=time
q= I t
q= 260 m t
The total number of electron = n
q= n e
![n=\dfrac{260\times 10^{-3}\ t}{1.6\times 10^{-9}}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B260%5Ctimes%2010%5E%7B-3%7D%5C%20t%7D%7B1.6%5Ctimes%2010%5E%7B-9%7D%7D)
n=162500000 t
![\dfrac{n}{t}=16250000](https://tex.z-dn.net/?f=%5Cdfrac%7Bn%7D%7Bt%7D%3D16250000)
The number of electron passe per second will be 162500000.
Complete Question
A 10 gauge copper wire carries a current of 20 A. Assuming one free electron per copper atom, calculate the drift velocity of the electrons. (The cross-sectional area of a 10-gauge wire is 5.261 mm2.)
mm/s
Answer:
The drift velocity is ![v = 0.0002808 \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%200.0002808%20%5C%20m%2Fs)
Explanation:
From the question we are told that
The current on the copper is ![I = 20 \ A](https://tex.z-dn.net/?f=I%20%20%3D%2020%20%5C%20A)
The cross-sectional area is
The number of copper atom in the wire is mathematically evaluated
![n = \frac{\rho * N_a}Z}](https://tex.z-dn.net/?f=n%20%20%3D%20%20%5Cfrac%7B%5Crho%20%2A%20%20N_a%7DZ%7D)
Where
is the density of copper with a value ![\rho = 8.93 \ g/m^3](https://tex.z-dn.net/?f=%5Crho%20%3D%20%208.93%20%5C%20g%2Fm%5E3)
is the Avogadro's number with a value ![N_a = 6.02 *10^{23}\ atom/mol](https://tex.z-dn.net/?f=N_a%20%20%3D%206.02%20%2A10%5E%7B23%7D%5C%20atom%2Fmol)
Z is the molar mass of copper with a value ![Z = 63.55 \ g/mol](https://tex.z-dn.net/?f=Z%20%3D%20%2063.55%20%5C%20g%2Fmol)
So
Given the 1 atom is equivalent to 1 free electron then the number of free electron is
![N = 8.46 * 10^{28} \ electrons](https://tex.z-dn.net/?f=N%20%20%3D%208.46%20%2A%2010%5E%7B28%7D%20%20%5C%20%20electrons)
The current through the wire is mathematically represented as
![I = N * e * v * A](https://tex.z-dn.net/?f=I%20%20%3D%20%20N%20%2A%20e%20%2A%20v%20%2A%20A)
substituting values
![20 = 8.46 *10^{28} * (1.60*10^{-19}) * v * 5.261 *10^{-6}](https://tex.z-dn.net/?f=20%20%3D%20%208.46%20%2A10%5E%7B28%7D%20%2A%20%281.60%2A10%5E%7B-19%7D%29%20%2A%20v%20%2A%20%205.261%20%2A10%5E%7B-6%7D)
=> ![v = 0.0002808 \ m/s](https://tex.z-dn.net/?f=v%20%20%3D%200.0002808%20%5C%20m%2Fs)
Your answer:
In Greek mythology, this constellation is related with the time the Olympian gods sought refuge in Egypt. Unfortunately, following their epic fighting with the Titans, peace did not closing for long, as the monster Typhon, son of the Titan Tartarus and Earth, sought revenge. Typhon was once a fearsome fire-breathing creature, taller than mountains and with palms which possessed dragons' heads in region of fingers. The Olympian gods sought to break out by way of adopting a number disguises: Zeus, a ram - Hera, a white cow, Bacchus (another model of the fable suggests Pan) a goat. As Typhon approached, Bacchus/Pan threw himself into the Nile but, in a panic, solely succeeded in altering part of his body, ending up with a goat's physique and the tail of a fish. Meanwhile, Zeus had been dismembered via Typhon, however was saved when Bacchus/Pan let out an ear-splitting yell, distracting the monster lengthy ample for an agile Hermes to gather the supreme god's limbs and cautiously fix him. In gratitude, Zeus transferred Bacchus/Pan to the heavens.
