Q:

The Kinetic energy of gas molecules

A) is unaffected by temperature variations B) decreases with increase of temperature
C) increases with decrease of temperature D) increases with increase of temperature
 
Answer & Explanation Answer: D) increases with increase of temperature

Explanation:

Kinetic Energy K.E = 12mV2  or 

K.E V2, Where 'm' is the mass and 'v' is the velocity of molecules.

 

Velocity is proportional to temperature. Hence, KE is proportional to temperature and would increase with temperature.

Q:

You have recently been promoted to a project manager for a clinical testing facility. The team is developing a new product that will cut down on testing interval requirements for a new seizure management medication. After you become involved with the project, you decide to add more research reports, which the customer did not request. This is an example of 

A) Good customer service scope B) Scope creep
C) Due diligence D) Gold Plating
 
Answer & Explanation Answer: D) Gold Plating

Explanation:

Answer A is incorrect because you are providing a service that the customer did not request; therefore, it might not be important to her and unnecessary. Answer B is incorrect because scope creep is generally an expansion of the scope of the project at the customer's request and the customer did not request these reports. Answer C is incorrect because an additional report does not always mean increased diligence with a project.

Q:

In a vacuum, all electromagnetic waves have the same

A) Velocity B) Wavelenth
C) Frequency D) All the above
 
Answer & Explanation Answer: A) Velocity

Explanation:

When traveling in a vacuum, electronic waves from the electromagnetic spectrum all travel at the same speed. Velocity is speed with direction, so they would all travel at the same velocity, realtively speaking. But frequency and wavelength are quite different.

Q:

How would you check whether the contents of two structure variables are same or not?

Answer

struct emp


{


     char n[20];


      int age;


};


main()


{


    struct emp e1 = {"Dravid", 23};


   struct emp e2;


   scanf ("%s %d",e2.n, & e2.age);


   if( structcmp (e1,e2) ==0)


        printf ("The structures are equal");


   else


         printf ("The structures are unequal");


}


structcmp ( struct emp x, struct emp y)


{


     if (strcmp (x.n,y.n) ==0)


           if (x.age == y.age)


            return (0);


            return (1);


}


In short, if you nee to compare two structures, you'll have to write your own function to do so which carries out the comparison field by field.
