Question

A square box of water has a small hole located in one of the bottom corner. When the box is full and sitting on a level surface, complete opening of the hole results in a flow of water with a speed $v subscript 0 end subscript$ , as shown in figure (1). When the box is tilted by $45 to the power of ring operator end exponent$ and half filled so that the hole is at the lowest point. Now the water will flow out with a speed of:

$v_{0}$
$\frac{v_{0}}{2}$
$\frac{v_{0}}{\sqrt{2}}$
$\frac{v_{0}}{\sqrt[4]{2}}$

The correct answer is: $fraction numerator v subscript 0 end subscript over denominator root index 4 of 2 end root end fraction$
