Hey AAKRITI I am getting this answer

 

 n=1]^{[b-1 ]} f(na/b) = (a)(b-1)/2

 

If you have the solution then plz post it.

Nice question prakriteesh !!

 

Here as per the given datas if we calculate 'g' at that place it comes to be 10m/sec2.

which is more than average 'g'. It is possible at poles only.

 

so, color of the bear must be white.

 

Plz correct me, if I am wrong or if I am right then plz rate my answer

 

cheers!!!!!! 

 

All of you, have a look !!

IF YOU DRAW A P-V GRAPH THEN AREA UNDER THE CURVE WILL GIVE YOU THE AMOUNT OF WORK DONE, WHICH IS MAXIMUM FOR ISOBARIC PROCESS. DO IT YOUR SELF AND SEE.

A perfectly black body absorbs all the radiations and afterwards emits this radiation, so a body which absorbs more will emit more, as according to Kirchoff's Law e/a = constant

 

where e  is emittance & a  is absorbance.

 

so answer is (a)

hydration enthalpy depends on size of the ion .smaller the size more the ion is hydrated & vice versa.

 

a)Na+ and Cs+

 

Na+ is having MORE negative H.E. than Cs+

 

b) K+ or Ba+2

 

K+ is Having more negative HE

 

c)Na+ or Mg+2

 

Mg+2 has more -ve H.E

since  F=ma;

 

therefore

 

As resultant force is 5N by vector law of llgm

 

therefore

 

a= .5 m/sec

 

therefore velocity after 10 secs is 5 m/sec

 

Now K.E is .5mv²

 Therefore

 

k.e is125 Joule

 

Can the function f(t) = sint + cost  ,      represent SHM ?

 

Plz explain in detail.
