What are (a) the lowest frequency (b) the scond lowest frequency and (c) the third lowest frequency for standing waves on a wire that is `10.0 m` long
Correct Answer - (a) `2.5 Hz;` , (b) `5 Hz` , (c) `7.5 Hz`. `v = sqrt((T)/(mu)) = sqrt((25)/((100 xx 10^(3))/(10))) = 50` `:. V_(0) = (v)/(2L) = (50)/(2 xx 10)...

Which of the following will have the most negative electron gain enthalpy and which the least negative? `P, S, Cl, F`. Explain your answer.
Correct Answer - D In chlorine, the addition of additional electron to larger `3p`-subsheel experiences less electron-electron repulsion than smaller `2p`-subshell of fluorine. Phosphours has very low electron affinity because there...

If a continuous function `f` defined on the real line R assume positive and negative values in R, then the equation `f(x)=0` has a root in R. For exam
(a) For `y= (x)/(k)` to be tangent to the curve `y=e^(x), k= 1//e`. For `y=e^(x)` to meet `y=(x)/(k)` at two points, we should have `k lt (1)/(e)` `" "rArr k...

If `y_(1)=max||z-omega|-|z-omega^(2)||`, where `|z|=2` and `y_(2)=max||z-omega|-|z-omega^(2)||`, where `|z|=(1)/(2)` and `omega` and `omega^(2)` are c
Correct Answer - C `(c )` We have `||z_(1)|-|z_(2)|| le |z_(1)-z_(2)|` and equality holds only when `argz_(1)=argz_(2)` `implies||z-w|-|z-w^(2)|| le |w^(2)-w| le sqrt(3)` and equality canhold only when `|z|=2` and not when...
