Answer:
The magnetic field at the center of the coil is 
Explanation:
From the question we are told that
The magnetic field of earth is 
The diameter of the wire is 
The radius is 
The number of turn is 
The current it is carrying is 
The earth magnetic field strength at the center of the coil is mathematically represented as

Where
is the permeability of free space
So



Answer:
if you mean the regions during slavery, North, but if in general, East. (think East Coast)
Find the electric flux and the disp at t=0.50ns
<span>Given: </span>
<span>Resistor R = 160 Ω </span>
<span>Voltage ε = 22.0 V </span>
<span>Capacitor C = 3.10 pF = 3.10 * 10^-12 F </span>
<span>time t = 0.5 ns = 0.5 * 10^-9 s </span>
<span>ε0 = 8.85 * 10^-12 </span>
<span>Solution: </span>
<span>ELECTRIC FLUX: </span>
<span>Φ = Q/ε0 </span>
<span>we have ε0, we need to find Q the charge </span>
<span>STEP 1: FIND Q </span>
<span>Q = C ε ( 1 - e^(-t/RC) ) </span>
<span>Q = { 3.10 * 10^-12 } { 22.0 } { 1 - e^(- 0.5 * 10^-9 / 160 *3.10 * 10^-12 ) } </span>
<span>Q = { 3.10 * 10^-12 } { 22.0 } { 1 - 0.365 } </span>
<span>Q = { 3.10 * 10^-12 } { 22.0 } { 0.635 } </span>
<span>Q = 43.31 * 10^-12 C </span>
<span>STEP 2: WE HAVE Q AND ε0 > >>> SOLVE FOR ELECTRIC FLUX >>> </span>
<span>Φ = Q/ε0 </span>
<span>Φ = { 43.31 * 10^-12 C } / { ε0 = 8.85 * 10^-12 } </span>
<span>Φ = 4.8937 = 4.9 V.m </span>
<span>DISPLACEMENT CURRENT </span>
<span>we use the following equation: </span>
<span>I = { ε / R } { e^(-t/RC) } </span>
<span>I = { 22 / 160 } { e^(- 0.5 * 10^-9 / 160 *3.10 * 10^-12 ) } </span>
<span>I = { 0.1375 } { 0.365 } </span>
<span>I = 0.0502 A = 0.05 A </span>
Kelly is pulling on the rock and the earth, but the rock's mass and the earth's mass overpowers her mass, so she is pushed up by the rock and earth.
Property of all ionic compounds make them electrolytes;
An electrolyte is a compound that conducts an electric current it is also in the form of aqueous solution or in the molten state, the ionic compounds are electrolytes because they dissociate into ions.
Explanation:
- Property of all ionic compounds make them electrolytes;
- An electrolyte is a compound that conducts an electric current it is also in the form of aqueous solution or in the molten state, the ionic compounds are electrolytes because they dissociate into ions.
- Most of the unique properties come from the hydrogen bonds which holds the water together.
- when a solutes break away from the crystal, the negatively and positively charged ions become surrounded by solvent molecules and it dissolves the ionic crystal.
