(a) Please show that the heat capacity at constant volume and constant pressure for air are given by,Cv=macvmwherecvm= (1 + 0.92

rv)cvdandCp=macpmwherecpm= (1 + 0.84rv)cpdIn the above equations, the mass of air isma=md+mv, wheremdandmvare the masses of dry air andvapor, respectively. The specific heats at constant volume and pressure for moist air (the combination ofdry air and vapor) arecvmandcpm, respectively. (b) The vapor pressure varies greatly in the atmosphere.At a temperature of 0oC, the vapor pressure can reach 611 Pa, while at 30oC, it can reach 4350 Pa. Howmuch do the specific heats at constant volume and pressure for moist air,cvmandcpm, vary at Earth’ssurface? Assume a surface pressure of 100,000 Pa.

Integrated circuits typically are mounted on ________, which are then plugged into the system board.
MrRa [10]

Answer:

chip carriers

Explanation:

The components of a transistor or an integrated circuit are contained on a chip carrier. It is also frequently referred to as a chip container or chip package. With the help of this packaging, the chips can be connected or plugged into a circuit board without risking damage to their delicate components. As chip carriers have shrunk in size to accommodate new technologies, the procedure of installing them has grown more complicated.

Define, in words the following i relative humidity ii) dew point temperature
defon

Explanation:

i) When we divide water vapor's partial pressure by the water's equilibrium vapor pressure at a given temperature we get relative humidity.

It is denoted by ∅

\phi ={\frac {p_ {H_{2}O} }{p_{H_{2}O} ^{*}}}

ii) When air is cooled so that it becomes saturated with water vapor the temperature where this occurs is called the dew point.

The six pilot certifications in the US are as follows:

  1. Sport Pilot
  2. Recreational Pilot
  3. Private Plane Pilot
  4. Commercial Plane Pilot
  5. Flight Instructor
  6. Airline Transport Pilot

From this listing, it is evident that the Private Plane Pilot is in the mid of the line so it is a mid-level position.
