Answer the following question either true or false *****
1) As long as a wave’s medium does not change in any respect, then the speedof that wave will not change.
2) According to Faraday’s Law, if the magnetic flux through some open area does not remain constant in time, then an electric potential will be induced in the closed path bounding that area.
3) Nearby but outside a charging capacitor (q > 0), the magnetic field has a magnitude of 0.
4) Inside a charging capacitor (q > 0), 0 Coulombs per second of electric charge flows from one plate to the other
5) In a circuit containing a capacitor, no current can flow through the wires until the capacitor is fully charged.
6) Given an n-dimensional region of space, the region’s boundary is a closed region of dimension n-1
7) A closed surface defines a unique volume
8) A closed path defines a unique area.
9) If an Amperian loop is drawn outside a charging capacitor, then the area bound by the loop must lie outside the capacitor
10) Inside a charging capacitor, 0 magnitude of electric flux flows from oneplate to the other
11) . Maxwell’s Displacement Current correction was added to Gauss’s Law and allowed Gauss’s Law to apply to steady currents.
12) According to the explanation of Maxwell’s Displacement Current, if the magnitude of an electric flux through an area changes in time, a magnetic field will be induced in the perimeter of that area
13) Mutually induced electric and magnetic fields must be perpendicular to each other
14) GIven the function I (t) = 1/6 at^3, no matter how many times you defferentiate with respect to (t ((dl/dt) , (d^2l/dt) (d^3l/dt),... ), you will never arrive at the answer "0"
15) GIven the function I (t) = 1/6 at^3t, no matter how many times you defferentiate with respect to (t ((dl/dt) , (d^2l/dt) (d^3l/dt),... ), you will never arrive at the answer "0"
16) If you find charge in some lab, you will necessarily find electric and/or
magnetic field in that lab.
17) If you find electric and/or magnetic field in some lab, you will necessarily find charge in that lab.
18) When electric and magnetic fields mutually induce each other in aperpetual pattern, that pattern satisfies the wave equation
19) 1/ squareroot of (epsilon 0 * mu0) = the speed at which mutually inducing electric and magnetic fields propagate through a vacuum
20) 1/ squareroot of (epsilon 0 * mu0) = the speed at which light travels through a vacuum
Explanation / Answer
1. Speed of a wave depends only on frequency and wavelength. So it's TRUE
2. The voltage Induced due to change in magnetic field is proportional to the change in flux. So it's TRUE
3. FALSE
4.The currents don't flow inside the capacitor so it's TRUE
5. It is FALSE becoz if it so happens there will be long term derlays
6 FALSE
