Imagine a skinny straw in the water, standing right over the hole. The WEIGHT of the water in that straw is the force on the tape. Now, the volume of water in the straw is (1 mm^2) times (20 cm). Once you have the volume, you can use the density and gravity to find the weight. And THAT's the force on the tape. If the tape can't hold that force, then it peels off and the water runs out through the hole. /// This is a pretty hard problem, because it involved mm^2, cm, and m^3. You have to be very very very careful with your units as you work through this one. If you've been struggling with it, I'm almost sure the problem is the units.

The expression known as Froude's number is given as Upper F equals StartFraction v squared Over gl EndFraction . This number wa

bearhunter [10]

Answer: $v=5.529\ m/s$

Explanation:

Given

number is given as $=\frac{v^2}{gl}$

and $number=2.6$

$l=1.2\ m$

g=acceleration due to gravity $(9.8\ m/s^2)$

calculating for $v$

$v^2=gl(2.6)$

$v=\sqrt{2.6\times 9.8\times 1.2}$

$v=\sqrt{30.576}$

$v=5.529\ m/s$

According to Newton's law of motion, when we shake a mango tree, mangoes fall down explain.

Reptile [31]

When we shake a mango tree, the mangoes fall down. It is because when we shake the tree, the mango tend to be rest due to inertia where as the branches are in motion. That is why the mangoes tend to be at rest due to inertia where as the branches are in the motion.
