Arrange in increasing order to `U_(av) U_(mp)` and `U_(rms)` .

When water rises in a capillary tube of radius r to height h, then its potential energy U_(1) if capillary tube of radius 2r is dipped in same water then potential energy of water is U_(2) then U_(1):U_(2) will be

A metal is illumimated by light of two different wavelength 248nm and 310 nm . The maximum speeds of the photoelectrons corresponding in these wavelength are u_(1) and u_(2) respectively . If the ratio u_(1) : u_(2) = 2 : 1 and hc = 1240 eVnm , the work function of the meal is nearly

A body of mass m is situated in a potential field U(x)= U_(0) (1-cos alpha x) when U_(0)" and "alpha are constants. Find the time period of small oscillations.

A point moves in a straight line under the retardation av^(2) , where 'a' is a positive constant and v is speed. If the initial speed is u , the distance covered in 't' seconds is :

Two particle of masses m_(1).m_(2) moves with initial velocities u_(1) and u_(2) . On collision one of the particles get excited to higher level after absorbing energy epsilon . If final velocities of particles be v_(1) and v_(2) then we must have :

The mass of nucleus ._(z)X^(A) is less than the sum of the masses of (A-Z) number of neutrons and Z number of protons in the nucleus. The energy equivalent to the corresponding mass difference is known as the binding energy of the nucleus. A heavy nucleus of mass M can break into two light nuclei of mass m_(1) and m_(2) only if (m_(1)+m_(2)) lt M . Also two light nuclei of massws m_(3) and m_(4) can undergo complete fusion and form a heavy nucleus of mass M ''only if (m_(3)+m_(4)) gt M ''. The masses of some neutral atoms are given in the table below. |{:(._(1)^(1)H,1.007825u,._(1)^(2)H,2.014102u,),(._(1)^(3)H,3.016050u,._(2)^(4)H,4.002603u,),(._(3)^(6)Li,6.015123u,._(3)^(7)Li,7.016004u,),(._(30)^(70)Zn,69.925325u,._(34)^(82)Se,81.916709u,),(._(64)^(152)Gd,151.91980u,._(82)^(206)Pb,205.97445u,),(._(83)^(209)Bi,208.980388u,._(84)^(210)Po,209.982876u,):}| The correct statement is
