Question 95 - The following formula is used as a reference : (analyte signal) / (internal standard signal) = (f-factor) x (concentration of analyte) / (concentration of internal standard). A solution containing 3 mM of analyte and 4 mM of internal standard gave peak signals of 2 and 3 mamps respectively. Another similar solution containing 2 mM of analyte and 1 mM of internal standard gave peak signals of 1 and 4 mamps respectively. Find the average f-factor.

Question 98 - The Planck-Einstein relation connects the particulate photon energy E with its associated wave frequency f to produce E = hf. Let h to be the Planck constant. The frequency f, wavelength L and speed of light c are related by E = hc / L. With p denoting the linear momentum of a particle, the de Broglie wavelength L of the particle is given by L = h / p. (a) Find the equation of E as a function of p and c. (b) If E has a unit of electron-volt and f has a unit of 1 / second, then what is the unit of h?

In an existing power plant (phase I) with step up transformers (3nos) with Ynd1 vector group to the 400KV bus bar,an extension power plant (phase II) with transformers (4nos) with Ynd11 vector group >. what are the consequences of such configuration ,please note that % impedance are also differ i.e. 15% & 10.5% the reason was that auxiliary supply interface is at different voltage levels i.e 400v & 6.6KV in phase i and phase II respectively .please advise ! Thank you !
