6.- La glucosa, uno de los componentes del azúcar, es una sustancia sólida soluble en agua. La disolución de glucosa en agua (suero glucosado) se usa para alimentar a los enfermos cuando no pueden comer. En la etiqueta de una botella de suero de 50 cm3 aparece: "Disolución de glucosa en agua, concentración 55gr/l".
a) ¿Cuál es el soluto y el disolvente en la disolución?.
b) Ponemos en un plato 50 cm3. Si dejamos que se evapore el agua , ¿Qué cantidad de glucosa quedará en el plato?.
c) Un enfermo necesita tomar 40 gr. de glucosa cada hora. ¿Qué volumen de suero de la botella anterior se le debe inyectar en una hora?.

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.
