I was working on the following problem from a textbook. The textbook has no answer. I have included my solution - I am not sure whether it is correct Any ideas and or solutions? (guidance)
Suppose that f is any function with domain (-infinity, +infinity)
a) Does the function g...
I gather the following:
- A decrease in atmospheric pressure leads to a decrease in boiling point
- Thermodynamics explains this using mathematics
- A kinetic theory model can also be used to explain
I need to know:
- The science behind this occuring. Why does a lower atmospheric...
I understand that liquid water cannot exists on Mars for extended periods of time because:
a) The atmosphere is too thin
b) Resulting in a lower boiling point water
c) Which leads to sublimification of solid ice into gaseous vapour
Quite specifically, I would like to understand the...
"Soda lime is 85.0% NaOH and 15.0% CaO. What volume of 0.500M Hydrochloric Acid is required to completely neutralise 2.50g of the Soda Lime?"
Hint: Consider the reactions separately
Formation of Soda Lime:
CO2 + H2O >> H2CO3
H2CO3 + 2NaOH >>...
I wish to understand why the speed of light slows down when it enters a medium such as glass or air.
Is this best understood by treating light as a stream of particles or a wave?
I have read that the speed of light (c) is a result of disturbance of the electromagnetic field. In contrast...
When studying advanced mathematics and physics do you find that your brain is quickly able to understand new concepts and complicated looking math equations on the page?
Is anyone here actually able to pick up a book, say "Linear Algebra" and read through it understanding it easily like a...
2.0g of pure undiluted HsSO4 is cautiously added to water and the solution diluted to 500 cm3. What volume of 0.1M potassium hydroxide, KOH, would exactly neutralise 25cm3 of the acid solution?
concentration = number of moles/volume
mass in grams =...
This is something I thought about while drifting off to bed last night.
Immediately after the period between the big bang and the formation of planets, how did these newly created planets enter their respective orbits.
I'm assuming the planets had different masses and that this was a...
I am a high school student with a general interest in physics of all types.
We have learned that circular motion is possible because of the centripetal force acting towards the centre. I gather that the centripetal force is the resultant of the gravitational and outward forces. The object...
I am having some difficulty understanding the concept of colour charge.
I realise that protons and neutrons are made up of a different number of quarks, and this is how they have the charges +1 and zero.
I then realised that different quarks have color charge and that in a hadron (protons...
I have been reading a paper which introduced classical mechanics concerning only one dimension. Before we get into anything about displacement and velocity, I read about dimensional analysis.
There is a section of the paper which isn't very well explained and I hope someone can explain it to...
I understand the physical changes in beta decay that eventually lead to the virtual particle, a W- boson being formed. However I do not understand the physical changes that take place, which eventually lead to an antineutrino being emitted. What changes take place in the W- boson, that make it...
I am interested in Quantum Mechanics and relativity. Because I am only fifteen I am unable to understand everything fully - however I usually get the main ideas and can understand the mathematics (unless it is very abstract - like matrix maths).
Everyday when I decide to read something about...
I have gathered that the orbit of an electron cannot be calculated due to the uncertainty principal which states that position becomes uncertain when momentum is measured and vice versa.
From this I understand that an orbit is not possible for an electron, hence the term...
Hello fellow physicists and mathematicians!
I am 15 years of age and trying to understand beta decay. At present I understand how the proton turns into a neutron etc... The problem is I do not understand how the decay of a W- boson turns into an antineutrino. I've read that the W- boson has...
