Understanding Scalars and Vectors
In this detailed video, we break down the key differences between scalars and vectors, and demonstrate how to find the resultant vector using both graphical methods (tail-to-head and parallelogram) and trigonometry. Learn step-by-step how to calculate magnitude and direction with real-world examples, including forces and displacement. Whether you're a physics student or just curious about scalars and vectors, this video will help you master the concept!

The Breathing System Overview
มุมมอง 1422 หลายเดือนก่อน
In this video, we explore the fascinating world of the breathing system, breaking down how your lungs work to keep you alive. From the journey of air through your respiratory system to the process of gaseous exchange in the alveoli, we cover it all. We’ll also discuss the impact of physical activity on breathing, the dangers of smoking, and how harmful chemicals in tobacco smoke can lead to lun...

who can reach 1 k ffirst me or u
nice video 👍
Next lesson please 🙏
Wow so good
It has helped me a lot 🎉 Thank you ❤
😮😮😮
Just what I needed for helping demonstrate this to my students. Thanks!
🤩
Thank you so much 😊❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
You're most welcome. I am glad you found it helpful..
Captivating lecture. For your surprise i can write the whole elements of the modern periodic table with respect to their symbol, atomic number, group, period, block, actinides & lactinides series( modern periodic table as it is) without seeing any written paper. Could anybody help met to participate in the global stage?? I am asking from my heart!!
I am in Grade 7 just started learning Biology. After watching this video I learn how to do the Dichotomous key. Thx for teaching!😁😄
Glad it was helpful. You are most welcome🙂
1 a. live in water....jelly fish b. live in land ...go to number 2 2 a. has legs...go to 3 b. has no legs...snake 3 a. has no wings...go to 4 b. has wings...butterfly 4 a. Give a birth ....lion b. Lay eggs ...tortoise
What if you have been given 2 organisms what do I do?
Typically the organisms should be three or more.. But if you are given 2 organisms, just have 1 step, 1a and 1b, mention contrasting features then identify each organism.. Hope this helps..
I am in class 8
Good
Thank you..
1a Terrestrial animal....go to 2 b Aquatic animal.... jelly fish 2a Animal with wings.... butterfly b Animal without wings....go to 3 3a Animal with legs ....go to 4 b Animal without legs....snake 4a Animal with a shell .... tortoise b Animal without shell ..... Lion
Well done!!
Is the potato chip boiled?
No, it is not boiled.
The 65th element should be Tb and not Te... The 81st element should be Te and not Tl.... otherwise, great video
Thank you...
I want a dichtomous key of a housefly,bee,cockroack,and a termite
ok
🎉❤
Thanks😊😊
Thanks there is very butifule
Welcome 😊
Thank you so much😅❤❤
You're welcome 😊
❤❤thanks 👍🏻
@@JulietMwavita 😊 always a pleasure..
Nice work 😊
Thank you😄
Really helpful! Keep it up
Glad it is helpful.. Thank you!
@@science_class264 you're welcome!!
keep on going! theseare so good ;)
Thank you so much.. I will do so.
what are the similar properties per each group that specifies each corresponding column in the periodic table of elements?
Good day @kisho2679, the properties of each group are discussed in the video from the time 4:32
Well, groups (column) of d-block and f-block are not (just transition metals as a whole are mentined, but not per family/column).
@@kisho2679 Okay, the f-block elements' properties are typically just distinguished from their periods because there isn't much difference from group to group so i will just discuss the d-block properties. group 3 (scandium group): soft, silvery-white metals, highly reactive with air and water, high melting and boiling points. group 4 (titanium group): high melting points, highly resistant to corrosion. group 5 (vanadium group): High melting points, hard metals, durable. group 6 (chromium group): very hard metals, high melting points, tungsten has the highest melting point of all elements. group 7 (manganese group): hard, silvery-white metals, high melting and boiling points, manganese has biological functions group 8 (Iron group): hard metals, some exhibit magnetic properties, they do not corrode easily, iron has biological functions, high density, high melting and boiling points. group 9 (cobalt group): resistant to corrosion and oxidation, display catalytic properties.
group 10 (nickel group): highly resistant to corrosion, used in catalytic converters. group 11 ( copper group): good conductors of electricity and heat, very malleable and is therefore used in electronics. group 12 (zinc group): hard metals, some are essential for biological functions, high melting and boiling points.
Dang, bro, this video is pure gold!🏆 It's insane how underrated it is, considering how awesome it is. Your breakdown of the periodic table was so slick and easy to follow. Seriously, thanks a ton for putting in the effort! Mad props to you, dude! Keep rocking it! 🎸🎶
Your comment made my day. Thank you so much😄
Overall, good video for a new channel. Some recommendation: May be do the intro shorter/ ditch it entirely. Please don’t do auto-generated voice. Better bad English pronunciation than this voice. Keep up with the good work!
Thank you for the recommendations. Will implement when i can..
good
Thank you.
perfect timing. i hv exams tmr🤣
All the best..
