How fast does water flow from a hole at the bottom of a very wide, 7.1 mm deep storage tank filled with water
trapecia [35]

Answer:

<h2>The water will move faster</h2>

Explanation:

This happens as part of the consequences of the continuity of an incompressible fluid, of which water is an example.

so as the water emerges from the wider section the flow velocity increases and vice versa.

Hence the flow velocity in indirectly proportional to the area

The continuity equation is given below for our analysis

A1V1=A2V2\\-------------------1

where

            A1= the area of the wider section of the tank

            V1= the flow velocity from the wider section

            A2= the area of the hole at the bottom

            V2= velocity of flow at the bottom.

Suppose 500 joules of work is done to push an object in 15 seconds. Find the power for this situation
ohaa [14]

Answer:

You have to calculate

Explanation:

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.
