Water is flowing through a horizontal tube having cross-sectional areas of its two ends being $A$ and $A'$ such that the ratio $A/A'$ is $5$. If the pressure difference of water between the two ends is $3\times 10^5\, N \,m^{-2}$, the velocity of water with which it enters the tube will be (neglect gravity effects)

Two spherical planets P and Q have the same uniform density p, masses $M_P$ and $M_Q$, and surface areas A and 4A, respectively. A spherical planet R also has uniform density p and its mass is $(M_P + M_Q)$. The escape velocities from the planets P, Q and R, are $v_P$, $v_Q$ and $v_R$, respectively. Then

Two electric bulbs marked $25W - 220V$ and $100W - 220\, V$ are connected in series to a $440\, V$ supply. Which of the bulbs will fuse ?

Two bodies $A$ and $B$ of mass $m$ and $2m$ respectively are placed on a smooth floor. They are connected by a spring of negligible mass. A third body $C$ of mass m is placed on the floor. The body $C$ moves with a velocity $v_0$ along the line joining $A$ and $B$ and collides elastically with $A$. At a certain time after the collision it is found that the instantaneous velocities of $A$ and $B$ are same and the compression of the spring is $x_0$. The spring constant $k$ will be
