A body is freely dropped from a height h above the ground. Find the ratio of distances fallen in first one second, first two seconds, first three seco
From second equation of motion i.e. `h=(1)/(2)"gt"^(2)(h=ut+(1)/(2)"gt"^(2)` and u=0) `h_(1):h_(2):h_(3)......=(1)/(2)g(1)^(2):(1)/(2)g(2)^(2):(1)/(2)g(3)^(2)=1^(2):2^(2):3^(2)......=1:4:9....` Now from the of distance travelled in `n^(th)` second `S_(n)=u+(1)/(2)a(2n01)` here u=0, a=g `S_(n)=(1)/(2)g(2n-1)` or `S_(1):S_(2):S_(3):......=(1)/(2)g(2xx1-1):(1)/(2)g(2xx2-1):(1)/(2)g(2xx3-1)=1:3:5.....`

Which of the following equation represents the motion of a body moving with constant finite acceleration ? In these equation, y denotes the displaceme
Correct Answer - C Acceleration `=(d^(2)y)/(dt^(2))` It is the second derivative where `t^(2)` terms can only survive and yield a constant value. Hence (i) represent the motion with constant finite acceleration.

The differential equation `(dy)/(dx)=(3y)/(2x)` represents a family of hyperbolas (except when it represents a pair of lines) with eccentricity. `sqrt
Correct Answer - B::D (2), (4) `(dx)/(dy)=(3y)/(2x)` `"or "int2xdx=int3ydy` `"or "x^(2)=(3y^(2))/(2)+c` `"or "(x^(2))/(3)-(y^(2))/(2)=(c)/(3)` If c is positive, then `e=sqrt(1+(2)/(3))=sqrt((5)/(3))` If c is negative, then `e=sqrt(1+(3)/(2))=sqrt((5)/(2))`

A dimensionally correct equation need not actually be a correct equation but dimensionally incorrect equation is necessarily wrong. Justify.
(i) To justify a dimensionally correct equation need not be actually a correct equation, consider equation, v2 = 2as Dimensions of L.H.S. = [v2] = [L2M0T2] Dimensions of R.H.S. = [as]= [L2M0T2] ⇒ [L.H.S.] = [R.H.S.] This...
