This isn't a homework but a discussion between my buddy and me. My hypothesis is that when I kicked against the wall, there is more efficiency in energy transfer, CPE --> KE than when I kick in water.
His idea is that when kicking the wall, it is a more inelastic collision and when kicking in...
So is it fair to say that heat can cause a magnet to lose its magnetism?
Also for part 2 of my question, when a magnet interacts magnetic material, eg a piece of iron, is the attraction mutual or is it only the magnet exerting magnetic force on the iron?
Homework Statement:: Is magnetism a property of materials? Can magnetism be increased, decreased or even completely removed from a material?
Relevant Equations:: Nil
Dear seniors,
This isn't my homework but this simple word "magnetism" has been bothering me for some time.
I know that a...
Hi everyone, I noticed something strange when I lifted my phone by its cable. My phone will remain connect to the cable for a few seconds before it disconnects and falls.
I understand that an object wouldn’t move unless a force has acted upon it. The fact that the phone remained connected for a...
I have been watching videos on the brachistochrone curve and from my understanding, the curve works as the ball goes through more acceleration at start, therefore causing it to reach the end the fastest. However, I understand that acceleration towards Earth is constant (9.81 m/s^2) and this...
Dear experts, please help me with this debate between my buddy and I.
I'm on the side that most mammals, like cats, dogs, humans and monkeys have 2 stage life cycle. Young --> adult and back.
My buddy says it should be 3 stage egg--> young--> adult and back.
We are both rather weak on...
I recently bought a toy that has this magnetic disc riding on a metal rail.

After letting it gain momentum, I tilted it downwards and let it climb and fall (making U shape paths) and then come to...
Thank you both for you fast reply.
My wife and I are both Science lovers so whenever sure things happen, we will be excited and confused as well due to our limited knowledge.
We have learned something interesting today.
Thanks again!
Hi all,
I recently encountered this scenario.
I placed a (1 litre) glass bottle with water (about half filled) that is corked up near my stove.
My wife was cooking and the cork suddenly popped.
We discussed this over dinner and I said that it was due the air in the bottle that has...
My wife was asking me if magnets are conductors of electricity and I told her magnetite isn't.
Then she asked me if an iron rod, after being magnetized is an electrical conductor. That got me stumped.
I am thinking by right it shouldn't affect the electrical conductivity of the iron rod...
Hi everyone, I need your help badly.
This may sound simple to everyone but I need to get the concept sorted out.
For ratios, we know that it is a comparison between 2 or more quantities with the same units.
My question is, can ratio be used to compare between say ingredients in a...
Hi all, I have just done a liquid separation of B-carotene and Chlorophyll-a and put the 2 samples through a UV spectrometer.
The result that I get from the meter for B-carotene is 448nm for 1st peak and 475.1nm for 2nd peak.
For Chlorophyll-a my peaks are at 417.9nm and 666.1nm.
But I...
hi all, i understand that maleic acid being in cis form is more acidic than fumaric acid.
is it due to the fact that because of the cis configuration, it can form intramolecular H bonds which then stablises the monoanion through resonance or?
then in the monoanion form, furamate monoanion is...
