Answer / sajil

ya deafnetly,anything less than atmosphere can be called as vacuum..

Answer / ankit negi

atm pressure is 1.013 kg/cm2 at sea lvel. at higher
altitudes atm pressure reduces,so a man at high altitude
will not be called in vacuum....

Answer / sudip bharati

vacuum is a negative pressure created by surrounding system
for their requirement, which is much or more less than the
atmospheric pressure. it is always measured with respect to
the surrounding atmospheric pressure either it is at hill
station or under the sea level.

Answer / renish

vacuum is always measured on sea/mercury level if atm
pressure is below some mmhg then its called vacuum

Answer / vaishtushar

Vacuum is space that is empty of matter.When the pressure exerting is much lesser than the atmospheric pressure then it is called vacuum.If it is slightly less than atmospheric pressure it is not called vacuum.fo ex at hill stationsthey are not living in vacuum.

ENGINEERING PHYSICS - EXAMPLE 30.3 : (a) The quantum number m is given by m = -s, -s + 1. If s = 0.5, find the values of m. (b) | T > = (cos T) | V > + (sin T) | H >. The V and H states form a basis for all polarizations. Let cos T = 0.8. (i) If (sin T)(sin T) + (cos T)(cos T) = 1, find the value of sin T. (ii) For | T > = a | V > + b | H >, where a x a represents the probability of | V > and b x b represents the probability of | H >. Which one is more abundant, | V > or | H >? (iii) Find the value of T without using any mathematical tools.

Question 71 - (a) The byte is the basic building block of computer data used in chemical engineering process simulation where 16 bits make a word, 4 bits make a nibble, 32 bits make a quad word and 8 bits make a byte. Then how many nibbles are there in a megabytes? (b) In computer data items, let : 1 bit - counts from 0 to 1, 8 bits - counts from 0 to 255, 16 bits - counts from 0 to A. What is the value of A? (c) In a binary system of 4 bits, if 1100 = 12, 1101 = 13, 1110 = 14, 1111 = 15, B = 16, then guess the value of B. (d) By using any form of tools, find the exact value of 2 power 64 or 2^64.
