Developing a civilization has something to do with the ability of the society of sustain the progress. A lot of factors like war, natural disasters, beliefs of the society etc could destabilize a budding civilization in its infancy. But it was also possible that an advanced civilization faced a...

The refrigerant in the condenser would always be in gaseous state once the liquid state refrigerant pass through the expansion valve. At start when Ti = Te, there would not be any difficulty for the compressor to suck in the gas from condenser and compress it.

did you mean 'subtract 36' ? [/color]

It is possible for an observer in an accelerating frame to clearly distinguish whether it is inertial with uniform gravity or non-inertial. the tidal forces localize the scope of equivalence principle over small distances. whereas in uniformly accelerating frame the there is no tidal force or...

I got at the most 3 dead in 4 months. May be someone can find more optimum way of finding out the poison with less casualities in less time. 1st month : 10 groups of bottles; 1 person for each group; 102 bottle in each group; (10 * 102 = 1020) ; 3 bottles reserved. 2nd month ...

How about this one : suppose it's 2:08pm and you're in ione, california. place an ad in the front page of every newspaper in the world (this requires lots of money--for someone like bill gates) that says the following: time travelers: go to ione california (give address) at 2:07pm and...

Hi, u consider a stationary ball 'b' directly below the falling ball and calculate the velocity of 'b' in + with respect to free falling ball. Else, if free fall is not crucial, vertical take off of a rocket (containing the ball) with acceleration 10 m/s^2. v = u + at = final velocity of...

As per SR, if we assume u r able to get velocity slightly slower than c, then according to ur dilated time of 1 sec the relative velocity of light is c with respect to u ( c is constant in any frame of reference ).

got myself burnt by a hot steam thro' the hole i made inadvertantly..! just joking.. no offence taken / intended..

Royce, Space-Time continuum is a curved surface. not curved space. there is no 'higher orbit' or 'lower orbit' on such a surface.

If the patient is terminally ill and aware that there is no hope to get out of misery, allowing him/her to die seems reasonable. but could not reconcile that it is not cold blooded murder from the doctor's perspective. the doc might feel he had to do that for his inability to avoid that.

Hi, For Q-1. Not sure. The propulsion device exerts force continuously but the object/child seems to exert in a burst. I'm not sure the populsion device could enhance the child's ability to exert more force. Q-2 Yes. under the setup the individual burst of the rocket add to the...
