How many of the following plants produce a composite fruit that develops from an inflorescence? Walnut,Poppy,Radish,Fig,Pineapple,Apple,Tomato,Mulberry.

If $a, b, c$ are three non-coplanar vectors,then the vector equation $r = (1 - p - q)a + pb + qc$ represents a

$A$ large open tank has two holes in the wall. One is a square hole of side $L$ at a depth $y$ from the top and the other is a circular hole of radius $R$ at a depth $4y$ from the top. When the tank is completely filled with water,the quantities of water flowing out per second from the two holes are the same. Then the value of $R$ is

The hybrids are generally found to be superior to their parents; this is because of:

$A$ prism of refractive index $\mu$ and angle $A$ is placed in the minimum deviation position. If the angle of minimum deviation is $A$, then the value of $A$ in terms of $\mu$ is :

$A$ body,thrown upwards with some velocity,reaches a maximum height of $50 \ m$. Another body with double the mass thrown up with double the initial velocity will reach a maximum height of $.......... \ m$.
