A 2.0 cm diameter faucet tap fills a 2.5 x 10-2 m3 container in 30.0 s. What is the speed at which the water leaves the faucet?

                      Speed of Water  =  2.652 ms⁻¹

Explanation:

Step 1: Calculate the Radius of the Faucet:

                       Radius  =  Diameter / 2

                       Radius  =  2 cm / 2

                       Radius =  1 cm or 0.01 m

Step 2: Calculate Cross-Section Area of Faucet:

                       Area  =  π r²

                       Area  =  π (0.01 m)²

Step 3: Calculate the Flow Rate (Q) as;

                       Q  =  2.5 × 10⁻² m³ / 30 s

                       Q  =  8.33 × 10⁻⁴ m³/s

Step 4: Calculate Speed of water as;

                       Speed of Water  =  Flow Rate / Cross-Section Area

Putting values,

                       Speed of Water  =  8.33 × 10⁻⁴ m³/s / π (0.01 m)²

                       Speed of Water  =  8.33 × 10⁻⁴ m³/s / 3.14 × 0.0001 m²

                       Speed of Water  =  8.33 × 10⁻⁴ m/s / 0.000314

                        Speed of Water  =  2.652 ms⁻¹

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

am i too late?
