Q:

The capacity of a water heater is measured in

A) Gallons B) Liters
C) Meters D) Both A & B
 
Answer & Explanation Answer: D) Both A & B

Explanation:

The capacity of a water heater is measured in Gallons or Liters. In the USA, it is measured in Gallons and in India, we measure it in Liters.

Hence, if the capacity of the water heater is 15 gallons or 15 liters, then it says that it can hold 15 gallons or 15 liters of water.

What three statements make up the cell theory?

A) All living things are made up of cells. B) New cells come frome exisiting cells.
C) Cells are the basic unit of structure/function in living things. D) All of the above
 
Answer & Explanation Answer: D) All of the above

Explanation:

The three statements make up the cell theory are::

 

1. All living things are made up of cells.

2. Cells are the basic unit of structure/function in living things.

3. New cells come frome exisiting cells.

 

These cells can vary widely, but all living things are composed of cells.

Q:

Point out the error, if any, in the following program.

# include "stdio.h"

main()

{

     FILE *fp;

     char str[80];

     fp = fopen ("trail", "r");

     while (!feof (fp))

    {

           fgets (str, 80, fp);

           puts (str);

     }

     fclose (fp);

}

Answer

The last line from the file "trial" would be read twice. To avoid this, ues:


       While ( fgets (str, 80, fp) ! = NULL)


               puts (str);

Q:

For Gamma radiation, what stops its penetrating abilities?

A) Lead B) Steal
C) Concrete D) All of the above
 
Answer & Explanation Answer: D) All of the above

Explanation:

The highly energetic gamma particles can penetrate most compounds that stop by other types of radiation. However, lead, steel, or concrete can reduce the high energy of these particles, making them less penetrating.

 

Hence, Gamma radiation can be stopped by a several inches of lead or steel, or several meters of concrete.

Q:

A parallel-plate capacitor of capacitance C1is  made  using  two  gold  plates.  Another parallel-plate capacitor of capacitance C2is made  using  two  aluminium  plates  with same  plate  separation,  and  all  the  four plates  are  of  same  area.  If gand aPare respectively  the  electrical  resistivities  of gold and aluminium, then which one of the following relations is correct?

A) C1>C2 B) C2>C1
C) C1pa = C2pg D) C1 = C2
 
Answer & Explanation Answer: D) C1 = C2

Explanation:

C1= capacitance of gold plates

C2=   capacitance   of   aluminium plates

rg= Gold’s resistivity

ra= Aluminium’s resistivity

As the capacitance depends on the shape,  size  &  geometrical  placing of  the  conductors  &  the  medium between them, hence, the value of capacitance  will  be  independent  of resistivity. Therefore, C1= C2

Q:

Which politician in British India had opposed to a Pakistan that would mean "Muslim Raj here and Hindu Raj elsewhere"?

A) Khan Abdul Ghaffar Khan B) Sikandar Hayat Khan
C) Maulana Abul Kalam Azad D) Rafi Ahmed Kidwai
 
Answer & Explanation Answer: B) Sikandar Hayat Khan

Explanation:

“Pakistan would mean a massacre,” the Premier of Punjab Sir Sikandar Hyat Khan predicted to the distinguished civilian Penderel Moon as early as in October 1938 ( Divide and Quit, page 20). That was well before the Muslim League adopted the Pakistan resolution on March 23, 1940, in Lahore, radically altering Sir Sikandar's draft just 24 hours before it was passed. He repudiated it because it dropped the organic linkbetween the two parts of India, which he had provided. He told the Punjab Legislative Assembly, on March 11, 1941, “We do not ask for freedom that there may be Muslim Raj here and Hindu Raj elsewhere. If that is what Pakistan means I will have nothing to do with it.”
