As we made advances in science we were able to distinguish between a normal and abnormal living things. Take humans for example,
we can see his/her physical properties(height,weight,eye sight,hearing etc etc) and say he/she is a
normal person. But still some babies are born with abnormalities.
How often this occurs? Does it come under six sigma?Do it apply equally to all living things? or is it species specific?

hi ,
we all know that the force is the rate of change in momentum and this happens if there is some velocity gradiend ,

but if we have a car with a uniform straight velocity and this car hits a wall , how can i calculate the force excerting by the car on the wall ?
note that : there is no momentum change as the speed is uniform,

please help !!!!

Why does it matter if something is water soluble or not when snorting it?

I was reading Wikipedia and I came upon this:

"As the name implies, "freebase" is the base form of cocaine, as opposed to the salt form of cocaine hydrochloride. Whereas cocaine hydrochloride is extremely soluble in water, cocaine base is insoluble in water and is therefore not suitable for drinking, snorting or injecting."

What does something being water soluble have to do with it being able to be snorted?

Recently, and I've always been told this by people who have, I guess, spiritual abilities, that my great grandfather is leading and guiding my life from beyond death. My mother also told me he was a very spiritual man, a shaman or something. Is he dictating what's happening to me? I know it sounds crazy to me, but honestly, can anyone tell me what's going on, or what's going to happen in my future, reading or something? My life has been very confusing and difficult as of lately, maybe it's because I'm a teenager, I don't know..but if anyone could help, I'd appreciate it. Thanks.

A house with a 16.2 × 103 ft2 floor area and 8.50 ft high ceilings is to be heated with propane. How many kilograms of propane would be needed to raise the temperature of the air inside the house from 63.0 oF to
73.0 oF ?. In this calculation your are ignoring the temperature of the walls etc.



The moloar specific heat of the air inside the house is 30.2 J mol −1 oC −1
The average density of air over this temperature range can be estimated to be 1.22 g/L.
The molar mass of air is 29.1 g/mol.
There are 28.317 liters in a cubic foot.
The molar heat of combustion of propane is −2220.047 kJ/mol
