Which excerpt from "I'm Not Thirteen Yet" is the best example of a first-person point of view?

Then Lynette and these new girls began holding thirteen-year-old clubs after school.
“This afternoon is going to so much fun,” said Lynette.
With spring turning to summer, the rift between the twelve- and thirteen-year olds grew worse.
Three weeks later, I reluctantly boarded the bus with all the other Shenandoah-bound kids.

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
