chmvijay · Answer

can you write the formula to find uncertainity in momnetum

anonymous · Answer

i donot know the formula

chmvijay · Answer

ΔX . ΔP =   h/4 *pie
do u know this

anonymous · Answer

yessssssss par value samj nhi arhi kya kismein put karooo

chmvijay · Answer

delta P kaa matalb uncertainty in momntum
tumko ΔX = 1 x 10-10 meter.  ΔP = ? find karna hai 
h constant kaa value malum hai naa

anonymous · Answer

6.626*10raised to the power-34js divided by 4 pie hoga na

chmvijay · Answer

h = 6.64 x 10-34 joule
chaloo calculate karke deltap kaa vlue batoo muje

anonymous · Answer

5.27*10-26kgms-1

chmvijay · Answer

aur eka baar check karo 10 raised ????check it once again

anonymous · Answer

10 raiesed to the power -26 hai

chmvijay · Answer

5.27 kyaaa
52.7 deko eka baar

anonymous · Answer

5.27 hai

chmvijay · Answer

nahiiiiiiiiiiiiiii
= 6.626 *10 -34 / 12.57 *10-10
=0.528 x 10-24 kg.m sec-1

anonymous · Answer

but answer yhi de rakha hai

chmvijay · Answer

but this is right answer 0.528 x 10-24 kg.m sec-1

anonymous · Answer

r u sureeeee

chmvijay · Answer

LOL iam sureeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee 100%

anonymous · Answer

kkkkk now next question plzz

chmvijay · Answer

that also u need to noo one formula try to find it

anonymous · Answer

do u know the second question i type

chmvijay · Answer

yaaa i know

anonymous · Answer

tehn plzz tell solution of tha t also

chmvijay · Answer

E =13.12*105J mol-1 / n^2
put n=2 and find E

anonymous · Answer

9.84*10 raised topwer 5 ayega

chmvijay · Answer

nahi yaar n^2 boletoo 2^2 kitna huaa

anonymous · Answer

4

anonymous · Answer

thereeee or nottttttt kya ayega naswer batona

chmvijay · Answer

13.12 / 4  kitna hua

anonymous · Answer

3.28

chmvijay · Answer

haa bara bara hai 3.28 *10^5

anonymous · Answer

kyooooo

anonymous · Answer

bataooooo ageeeeee

anonymous · Answer

aap na plzzzzzzz mujhe jaldi se questions ke answer batdo

i will be thnkful to u then

chmvijay · Answer

answer too batawoo muje

anonymous · Answer

how much water is formed by mixing 100g h2 and 100 g 02????????

chmvijay · Answer

LOL

anonymous · Answer

kyaaaaa huaaaaaa ab yeh nxt question hai

anonymous · Answer

whttttt happnd nowwww

anonymous · Answer

thereeeee or notttttttt

This is so funny!  A chemistry explanation in hindi on a site that claims to be English only!
Another #onlyonOpenStudy moment!

chmvijay · Answer

Is it ok to use Hindi or should we be strict to English!!
because some  students understand better in their own language !!

nincompoop · Answer

Engdi is okay to use.

mathslover · Answer

Haha, Nice tag @Preetha mam : #onlyonOpenStudy Moment! :)

anonymous · Answer

The second question can be determined by looking at the bohr equation and determining the bohr radius for n=2 orbit. I don't think the application of a ratios would work in this case, as if I'm not mistaken E depends on the square of n.
Good luck
