Great explanation. You have explained the properties of laser very well amd depth. Thank you!

Radioactivity basically is like popcorn🥰

Can you please explain what is "U"

Great video- i learned something that I knew but could not confirm. You missed a great opportunity to tie it to E=mc2

is this for detection of only malignancies or benign tumours can also be detected?

Thank you

Not a concrete block - sandstone.

great video sir

I think you could explain the direction of induced current using Fleming's right hand rule. Remember that motion is in the direction of the conductor. Relative to the magnet, the conductor is moving upwards (you could explain this to a student to imagine that you are holding the magnet still and pull the tube upwards), now you can use first finger = field and thumb = motion to obtain the correct direction.

I made it and it works! Thanks.

This is interesting but I had to watch at 1.75x

that tshirt looks cool somehow

very good video!

trigger warning!

Great! Please show us more results, though!

My teaches better than this.

You didn't explained it well😢😢😢.

Thanks sir

Amazing

This is really lousy science... -Ether could move with the Earth like air. You don't get different speeds for sound because of earth orbit/rotation because air travels with earth... -The experiment wasn't even done in a vacuum... it was done in AIR!!! So it's not even clear if you're testing light in air + ether, or just air. They could have at least done it in a vacuum, that technology existed at this time. -Air has refractive incidence, and light speed is not invariant in a medium. Which is why relativity is also lousy science. To the guy who made the video, great video! Very well explained. Maybe could have included better explanation for why it would slow down though along yellow line. Intuitively most people would assume the negative speed moving against wind would balance out with positive boost moving with wind. As a cyclist I definitely wouldn't expect them to balance out hahaha, riding with and then against wind is overall slower than having side-wind, I would expect yellow to be slower as they predict, I believe it's because wind resistance is exponential, not linear. Higher speed takes more energy to accelerate so smaller boost from wind supporting you, than resistance added from wind opposing. Does the math indicate something similar?

Some time ago I was looking at using plasma balls as instruments/interfacing devices. The real problem seems to be in calibrating (coz of whatever error, such as manufacturing, environmental variation, etc) as best as possible and then correlating/assignment along with differentiating

so good and clear, thank you:)

At 4:07 you say "Can I make it absolutely clear, we do not have a back current". Are you saying that the back EMF doesn't produce a current that opposes the source current? I was taught the net current = source current minus back EMF current. Is this correct?

That unit with solar panel with speaker , what is it called ? And if you can give link to purchase this with light modulator flash . Thanks..link in description is not working

Thanks for making this video:) I'm currently going through a mental breakdown, and learning about radioactivity calms me down a lot:3

This really helps. Thank you.

Best video for my son

Could you wave your hands any more please?

this experiment proves Earth is flat! Yessss

Space energy is greater than light energy source & light energy is greater than light energized matter

Thank you Paul for making things appear more easier then it looks like.

this man knows what he is talking about unlike my physics teacher in university .

Is there ever more than 2 dees? Also do the dees typically use sine ac or square wave?

how are you writing backwards

Wasting money in truck load. They dont split atoms. hitting proton with proton and making up nonsense particles

Are you sure the answer is B? I picked B but everyone who did physics in my school said the answer was C… q20.

I was leaning towards B for Q20 but the higher instantaneous velocity of Z(longer circumference, same orbital period) than X gave me pause for thought.

What do you think of this paper in terms of the other years. Was it hard?

What was the impact speed of Dale Earnhart's car when it hit the wall at Daytona?

Now you just showed the rest of the world why physics is wrong where you live----you're sitting on the wrong side of the car and driving on the wrong side of the road, LOL.

in the example problem, i’m having a hard time understanding how the magnetic field is opposing the change in the initial magnetic field. i understand the explanation of how we get the direction going upwards inside the coil, but how does this support lenz’ law where “the magnetic field created by the induced current opposes changes in the initial magnetic field” if there are portions of the magnetic field that are actually in the same direction (like inside the coil)

thank you sir for your perfect lecture about this concept

Thanks to you, I got the help I needed

Guys im cooked I got my exam in a week

JESUS ❤is King AMEN

This is super cool!

4:56/ 13:54 An electron which has absorbed a photon : changes its energy, discreetly changes its orbit ; and then receives a second photon which causes it to emit COHERENT LIGHT" That inexplicable coherence is gives rise to the "quantum effect " .... Q: that COHERENCE NO logical explanation A : The invention of quantum theory has been invented to satisfy why COHERENCE is created ; why the LASER exists ! too many theories look for a better answer.

thankyou very much. appreciate your explanations.
