5 0

Answer:

Correct answer is option B (The reason for using supertypes is to minimize the number of nulls and to minimize the likelihood of redundant relationships)

Explanation:

Entity supertype

A  entity supertype is a generic entity type which is related with one or more subtypes.

Use of entity supertype:

The reason for using entity supertype is to reduce redundant relationships and it is also used to minimize the number of nulls.

Zanzabum

Answer: (B) Branch cache

Explanation:

  The branch cache is the process of cache the data from the given file and the wen server on the wide area network. In the WAN connection, the branch code is the type of functionality which basically allow the window to providing the remote user support in the network. The branch cache basically work on the two mode that are:

  • The distributed mode
  • The host mode

The branch cache is the one of the technology that intend the cache data for reducing the network traffic in the wide are network.

Therefore, Option (B) is correct.

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use
jeyben [28]

Question:

Define a function compute_gas_volume that returns the volume of a gas given parameters pressure, temperature, and moles. Use the gas equation PV = nRT, where P is pressure in Pascals, V is volume in cubic meters, n is number of moles, R is the gas constant 8.3144621 ( J / (mol*K)), and T is temperature in Kelvin.

Answer:

This solution is implemented in C++

double compute_gas_volume(double P, double T, double n){

   double V = 8.3144621 * n * T/P;

   return V;

}

Explanation:

This line defines the function, along with three parameters

double compute_gas_volume(double P, double T, double n){

This calculates the volume

   double V = 8.3144621 * n * T/P;

This returns the calculated volume

   return V;

}

To call the function  from the main, use:

<em>cout<<compute_gas_volume(P,T,n);</em>

<em />

<em>Where P, T and n are double variables and they must have been initialized</em>

What is the LER for a rectangular wing with a span of 0.225m and a chord of 0.045m
ch4aika [34]

Calculate LER for a rectangular wing with a span of 0.225m and a chord of 0.045m. The weight of the glider is 0.0500 Newtons. (Note: the wing span is the width of the wing and is measured from wing tip to wing tip, or perpendicular to the fuselage. The wing chord is the length of the wing measured parallel or along the length of the fuselage.)

Answer:

Area of rectangular wing = span × chord = 0.225×0.045= 0.010125m2

LER = Area/weight = 0.010125/0.0500 = 0.2025

PLSSSSS HELPP!! Population biologists are concerned about invasive species such as the zebra mussel found in North American wate
elixir [45]

Answer: A.The introduced species compete for resources more effectively than native species.

Explanation:

An introduced species is also called the exotic species and this is an organism which is not a native organism or specie and therefore isn't native to the place but rather it's being transported to the place through the activities of human being.

When the introduced species are introduced to a particular area, they compete with the natives for the available resources and often do this more effectively than the other native species.

Therefore, the correct option is A.
