Consider the following statements.<br>1. SI unit of atmospheric pressure is Nm<sup>-2</sup> or pascal and CGS unit is dyne/cm<sup>2</sup>.<br>2. The barometer is a device by which the atmospheric pressure is measured.<br>3. The standard atmospheric pressure is the pressure required of 76 cm of Hg column or 760 mm of Hg column, which is equivalent to 1 atm.<br>Which of the statements given above is/are correct?

Correct Answer: 1, 2 and 3

A student wants to find the absolute pressure of water at a point below the surface of water. He has a barometer and a manometer pressure gauge. The barometer reads 1.3152 bar where as the manometer pressure gauge reads 0.3152 bar. What is the absolute pressure? (Assume that pressure at one end of the manometer is atmospheric.)

Consider the following statements.
1. In case of standard assets, provision for NPA must be 25% for all types of standard assets.
2. In case of sub-standard assets, provision for NPA must be 10% for all types of standard assets.
3. In case of doubtful assets, 100% provision is required for unsecured and secured advances.
4. In case of loss assets, 10% of unsecured and 100% of secured advance must be kept as provision for NPAs.
Which of the statement(s) given above is/are correct?

In the previous question Air is trapped in the space (labelled A) above the mercury level in the tube of a barometer, which measures 750 mm Hg. If the atmospheric pressure is 760 mm Hg, then the pressure of the trapped air is

Directions: Seven different boxes A, B, C, D, E, F and G of different colours viz., Orange, Pink, Purple, Yellow, Blue, Red and Green are arranged one above the other. The box at the bottom of arrangement is numbered 1, the above box is numbered 2 and so on. B is immediately above E. More than two boxes are above the Orange box. The Yellow box is immediately below A. Only one box is between the Orange box and F. G is immediately above the Red box. Only one box is between B and the Pink box. Only two boxes are between the Pink and the Green box. Only two boxes are between the Yellow box and the Orange box. The Purple box is neither at the top nor at the bottom of the arrangement.B is above Pink box. C is immediately above F. Neither C nor G is a Yellow box. G is not a Orange box. Question: Which combination represents the position of C and its colour?

While measuring the output load capacitance Cgs, n and Cgs, p is not considered. Why?

During the calculation of load capacitance of a 1st stage CMOS inverter, the input node capacitances, Cgs, n and Cgs, p of the 2nd stage CMOS inverter is also considered.

In the following question, two statements are given each followed by two conclusions I and II. You have to consider the statements to be true even if theyseem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement:
(I) Children start writing with a pen in sixth standard.
(II) Ink pen is prescribed by most of the schools for school kids to write with as it maintains the handwriting and comfort of child. Conclusions:
(I) Till fifth standard kids are unable to use pen on their own completely.
(II) Ink pen maintains a proper flow of ink on paper and takes less effort to put words on paper.

Consider the following statements regarding ICAO recommendation for correction to basic runway length of these statements
1. The basic runway length should be increased at the rate of 7 percent per 300 m rise in elevation above the mean sea level.
2. The basic runway length after having been corrected for elevation should be further increased at the rate of 1 percent for every 1°C rise in airport reference temperature above the standard atmospheric temperature at that elevation.
3. The runway length after having been corrected for elevation and temperature should be further increased at the rate of 20% for every 1 percent of effective gradient.

A,B,C,D,E,G and I are seven friends who study in three different standards namely 5th, 6th and 7th such that not less than two friends study in the same standard. Each friend also has a different favorite subject namely History, Civics, English, Bangla, Science , Maths , and Economics but not necessarily in the same order. A likes Maths and studies in the 5th standard with only one other friend who likes Bangla. I studies with tow other friends . Both the friends who study with I like languages (Here languages include only Science , English and Bangla ) . D studies in the 6th standard with only one person and does not like Civics . E studies with only one friend . The one who likes history does not study in 5th or 6th standard . E does not like languages. C does not like English , Science or Civics. Which combination represents E's favorite subject and the standard in which he studies?

An apple contains 70% of water which has to be dried at 100°C down to moisture content of 15%. If the initial temperature of the food is 21°C, The latent heat of vaporization of water at 100°C and at standard atmospheric pressure is 2257kJkg-1. The specific heat capacity of the food is 3.8 kJkg-1°C-1 and of water is 4.186 kJkg-1°C-1. Calculate the quantity of heat energy required per unit weight of the original material, for drying under atmospheric pressure?
