Due to what core component is emotional intelligence critical to effective leadership?

How do convection currents in Earth's core produce the magnetic field?

In a step index fiber, the index of refraction undergoes a discontinuity (jump) at the core-cladding boundary, as shown in the figure. Infrared light with wavelength $1550 \mathrm{~nm}$ propagates through such a fiber by total internal reflection at the corecladding boundary. The index of refraction of the core for the infrared light is $n_{\text {core }}=1.48$. If the maximum angle, $\alpha_{\max }$, at which light can enter the fiber with no light lost into the cladding is $\alpha_{\max }=14.033^{\circ}$, calculate the percent difference between the index of refraction of the core and the index of refraction of the cladding.

Write the chemical formula for the ionic compound that would form from the elements X and Z if

c. X has three valence electrons and Z has five valence electrons

d. X has six valence electrons and Z has two valence electrons

Explain why the inner core remains a solid even though it is very hot.

Electrons move as a current from a battery to a lightbulb. What happens to the electrons when they reach the lightbulb? $(a)$ The electrons are used up. $(b)$ The electrons stay in the lightbulb. $(c)$ The electrons are emitted as light. $(d)$ Fewer electrons leave the bulb than enter it. $(e)$ None of the above.
