You are my favourite person on RU-vid, honestly! My physics teacher is impatient and very unapproachable, and I tend to need someone to explain things slowly for me... which you do perfectly! You're an absolutely wonderful teacher :)
Rock sample containing radioactive element -old ( 1500 million years ) . If the ratio between the radioactive and stable component Component (1: 7) Calculate the half-life of the radioactive element
Very helpful. Can you please cover the next lessons because I have a test on have life's that may involve more complicated equations. P.s I love your videos.
Half life calculations using exponents and logarithms you said would be in the next video. I did not find those. Could you pl let me know the where they are?
How would you figure out the age of a rock given only the percentage of uranium-238 left and the half life of uranium-238???? I've tried everything and can't figure it out or find resources to help
You are the one person I actually ALWAYS understand. I could not be more grateful for your videos. PLEASE, just keep doing this, you really shape knowledge.
Baggie Watch it again by looking at the problems and the question in more detail. I didn’t understand too but when I relaxed myself to understand it was easy
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Life saver! Your teaching method is absolutely amazing. You videos fall me in love with physics. I am very grateful to you. Thanks a lot once again. Do you have o level physics notes??
geronimo miranda Yes. Most of the time, you are NOT expected to know this. Usually these details will be given to you. Even your professor won't know half lives of each atom. I would not worry about that. Good luck :)
It is not a good idea to use half lives to do these calculations as there will always be a case where the times do not work out so conveniently. Also, it assumes that the decay occurs in a periodic manner when it is a continuous process. Far better to use the exponential formula and the decay constant lambda; Nt = Ne^(-lambda*t)
To me the easiest-to-use formula is time = (number of half lives) x (length of a a half life). There is a fancier one with exponents, but this works like 95% of the time.
Our education system sucks. My chem teacher always goes off on stupid personal stories/political rants and I learn nothing. You are a great teacher, thank you.
Yo how do you split numbers in half like that perfectly when it gets to the decimals? To be honest it's probably common knowledge, but my school didn't even bring up simple things like division until 9th grade
I need help with a work!! I need help like ASAP!! If you can assist me I would appreciate it!.. In 20 days, the activity of a sample of Bismuth decreases to one-sixth of its original activity. Calculate the half life of Bismuth. please help me!!!
Dude I'm new to this but the sample of hydrogen.... isn't it 61.3 years? I really appreciate the videos too.... you explain things so well. Thanks man 😁
Um good video but like isn't there a formula that we should use . Is there a difference between half life calculations and nuclear half life calculations?
Tyler you are great at explaining and it's personally helped me out a lot, but it looking at your videos you use a ton of paper; so wouldn't it be better if you could use a large ipad or screen to explain
Its fascinating that the rate of decay is so regular, I wounder if you added a bunch of energy (heat) to it if it would decay faster or have any effect at all.
