in certain problems, we assume the normal force to be equal to the weight, like in friction problems,are we neglecting centripetal force here?

In case it is not clear, Solution(2), we use the theta= 30 and plug it into V_bR*costheta to find the vertical component/component crossing the river.

An awesome EE prof! Really appreciate it. Thank you.

Kinda nuts this college kids think about everything so mathematically. I haven’t finished the video but I’m pretty sure the answer is basically zero. If you are in the dead center of the earth you’d be so close to the core gravity would not be pulling you anywhere. You’d be essentially weightless. Maybe I’m wrong

initial velocity would be changed at the last part right ?

Full video please

Amazing❤2024

Call me crazy but I just binge watch his content for fun😭😭 They're so interesting

I dont even know why i searched up for this

Sir one doubt,,,how was electron loss in the electric field not a conductor 😊😊

its an impressive lecture but i have never understood why they compress all these stuff in one semester😭

Where did you get that writing board??????

WHAT THE FUCK IS THIS SHIT 🗣️🗣️🗣️🗣️‼️‼️‼️‼️‼️

sir I'm from India and I watch your lectures definitely helps me thanks

Why does reflecting of em waves from a particular sized obstacle depend on wavelength of wave instead of its amplitude ? As those are transverse in nature...

I love the gradually built-up explanation of this equation, so that you can clearly understand where a certain parameter comes from and how it relates to other parameters

Wait a second... is this guy writing backwards?? Or did he just mirror the video? Either way, I love it lol

Nice explanation thanks

Cool blackboard set up :D

My 1st year engineering lecturer made me hate physics, you have restored my love for physics

How does he write on the board so it's legible for people in the front? does he write backward?

i would sell my kidney to have you as my physics lecturer (for legal reasons, this is a joke)

BTW if I is zero in the plastic loop due to infinite R then Ohm's Law says V= IR = zero * Infinity = ZERO. No?

The Inductor converts part of the electric current called (I)=Q/t to magnetic flux (BA) . The magnetic field (B) itself is not energy. Energy (E) is a PRODUCT of the current (Q/t) and magnetic flux (BA). Thus E = 1/2 Q/t * BA or 1/2 (I )* BA. So B is just one factor of the energy equation. It is wrong to imply that B is energy or contains energy. Surprisingly B boils down dimensionally to 1/t or the reciprocal of time. The stronger the B the shorter the time interval and greater the velocity, acceleration, voltage and energy where time is the denominator. Furthermore since E = 1/2 current * BA then for a GIVEN amount of E, when B or BA is increasing current or Q/t will be decreasing and if BA is decreaing then current must increase. L is just BA/I (in Ohm Sec) so E - L* I^2 = the old BA* (I). Point is the inverse relationship between BA and (I) for a fixed E does not require manufacturing te negative feed back of Lenz. because when E is fixed BA and (I) are MATHEMATICALLY inversely related. Analogous to F=ma.. Afterall there is no Lenz for F = ma is there?

~ That perfect circle tho

Are you a biologist as the speed and listlessness seems

Comparing 4:18 with 5:10 - uhh, no? 16*10^2 == 1600 ... you were off, but not by any orders of magnitude.

What is reason behind thi

OMG! At 50:28 he flouts Ohm's law claiming V or EMF being positive despite admitting that I is zero due to infinite R. But zero I * Infinite R = zero EMF since mutiplying ANYTHING by zero = zero. Just check the plastic hoop by a voltmeter. Will the secondary coil of a transformer develop a voltage if made up of non conducting plastic? Nevertheless the rest of the lecture is very good.

Pretty good so far (35:47). Describes Lenz coventionally instead of saying that B flux like momentum is a conserved quantity.

What of the one with unit of J/m³

This may be a dumb question, but how come if I block half of the lens of my glasses, i only see half the image? Is it because my eyes are directly behind it? Also, what happens if instead of blocking the bottom half, you block the center 50% of the lens (inner circle)?

mmmkay

Thanks Sir

I need that board!

You’re great thank youuu😄🙏🏼

👉 ഫലം🥭🍎🍈🍊🍋🍌🍍👈👉😂

I work in VR domain and I was trying to understand lenses in VR headsets. These fundamental concepts on optics have been very very helpful. Thanks for putting these.

Do we believe that all the interiors of the earth rotate relative to each other as a solid mass or do they spin at different rates as you reach the core?

what would be the experienced difference between two vacuum tunnels where one is from north pole to the south pole and the other tunnel is from a spot on the equator to the opposite spot on the equator. That is to ask: how would the earth's rotation affect the result?

does this apply if there are no resistors in the circuit?

When you realize he’s writing backwards 👀

Good video , but it Would have been better to do some problem solving at the end of the video

great!

I was lying on bed about to go to sleep and i said let me just watch this video because i have final exam next week! And guess what? The best thing i did Thank you so much legend

I was surprised that I as bus driver knew it was 0 because it was only logical but some students said stupid things :(

how the fuck is he written in the opposite direction

Thank you , but I really so no meaning of knowing what d is because there is no need for it in the formula😂

What is the difference between mass of electron and proton,why neutron has no charge?
