Describe the implementation of vapor-liquid-solid (vls) method to grow a
nanowire. indicate what are the key ingredients or processes involved?
when a nanoparticle is subject to optical characterization, its spectra often show blue or red-shift comparing with its bulk counterpart. list the possible reasons in optical ranges of the visible and the infrared, respectively.

You are given a vector a = 125i and an unknown vector b that is perpendicular to a. the cross-product of these two vectors is a × b = 98k. what is the y-component of vector b?

Argon, neon, and xenon are examples of

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
