Lots of prayers for you.May Allah give you every type of happiness. King

[Faizii-bn]

hello sir, MCQ 8 ka correct option A ha , ,neutron can ionize a gas as they have momentum, here the option is they cannot ionize a gas, that is inncorrect, so, A is correct option, while the other you choose, neutron use in both in fusion as well in fission reactions

[ahmedmunaf]

Jazak Allah sir dil s duaeyn niklti h Allah apko jannat m horraindain ameen

[bilawalvlog]

Colour in discharge tube depends on the nature of gas filled in discharge tube

[ShayanMallah-lqnp]

34:28
when the velocity of the photon is doubled the wavelength also gets doubled. Thus, the velocity of a photon is dependent on the wavelength
sir plz aagr main sahi keh raha hoo tu like krdein
😇😇

[saminakousar]

Velocity depends on wavelength if frequency kept constant, hum yeh cheez tab partein hei jab wave aik medium sy dusry mei jahe..

[hussanbano]

Sir velocity depends on wavelength because wavelength us inversely proportional frequency

[FidaBalouchvloger]

Let me explain you,
That velocity is independent of wavelength.
V=lambda × frequency
So if increase lambda then frequency decreases and cancel each other and net effect becomes zero

[shezirajput-zdbu]

Sir velocity is dependent on wavelength directly to frequency when frequency constanat vrlocity directly proportional to wavelength

[bilawalvlog]

Photon ki velocity constant Hoti he (it's magnitude equal to speed of li8) so option a is correct

[NkB]

Sir question number 13 shayad apneinen ghlt tick ki
Sir mere khayal mien glow depends on pressure but colour of Glow depends on the gass present inside the tube....

[AbdulRazaqueQureshi]

The splitting of spectral lines when atoms are subjected to strong electric field....sir Zeeman effect hoga

[ShayanMallah-lqnp]

sir plz nums key bhii pastpaprs solvee krwayeein

[drhuriyamustafa]

When a matter move with a speed of light it is called de brogile waves so opt d should be correct

[Reelico-stoodio.]

Sir Glow of depends upon.gas filled in the tube book main yahi likha hua...aur aap keh rahe hain ke pressure pe depend krta hai..which one is correct

[zahraali]

sir isi tarha saray chapter ki video upload kar dain please

[editinglab.]

Sir color of rays are dependent on nature of gas used

[Paribaloch-qt]

Yes sir plz ulpoad the mcqs of sindh accadmy umerkoat sepecially organic chemistry

[kabeerkumar]

Sir Asalamwalikum Sir Jo Nts wala Question hai us main B Option Correct hoga sir ptb book ki Digram main mention hai Postive half Anticlockwise rotation ko Show karta and Negative half clockwise rotation of electron ko Show karta hai Sir Please bataiya ga agr mera Option. right hai too

[Saifullah-nmlf]

Sir Please Baki sare chapters Bhi Karayein if you want stb mcqs i will send u
