isobutyl coz 3>2>1 in case of Sn1

particle of light are called photons that are just an assumption to explain photoelectric effect carrying energy hv. of zero rest mass.so we cant catch them. get yourself acquainted to the photoelectric effect.. long live einstein

heres a thing dont waste mone on some lame coaching centre ... read NCERT first then slowly increase levels on books ... once you r completed opt for test series and you will rock the world

stop worrying and get a M.L. Khanna and Arihant(goyal) do dem and rock the world

u=-80 r=-40

v=-80/3

vifferentiating both sides W.R.T time

we get

velocity of the image

distribute 3 balls from 8 to three of them then distribute 5 balls randomly

thus

7C2=21

thus 21 is the answer

5! onwards every valuse is divisible by 20so 1+2+6+2433-20=13 remainder

i think he has made his decision and studing in 2nd year at sum college for god sake it was 2009

Prove that 33! is divisible by 2¹⁵. What is the largest integer n such that 33! is divisible by 2ⁿ?
Plz give detailed ans.

circles with centres at 1,2 and 2,1 and radius 1 unit

let the plane parallel to r.(3i + 2j - 2k) + 15 = 0be 3x++2y+2z=mputting (3,8,2)we get m=21nowx=1+2ky=3+4kz=2+3kwe get k=2and (5,11,8)distance between the given point and the aboveis 7 units
