Answer:
The pressure inside the hose 7000 Pa to the nearest 1000 Pa.
<em></em>
<em></em>
The pressure at the site of the puncture is <em></em>
Explanation:
<em>According to Poiseuille's law, </em>
<em>Where is the pressure at a point before the leak, is the pressure at the point of the leak , μ = dynamic viscosity, L = the distance between points and , Q = flow rate, D = the diameter of the garden hose. </em>
<em>Also, from the equation , the equations and can be derived.</em>
Combining Poseuille's law with the above, we get
<em></em>
<em></em>
Since the hose has a uniform diameter, the nozzle at the end is closed and neither point <em> nor lie after the puncture,</em>
<em></em>
The pressure at the site of the puncture <em></em>

Answer:
By observing the color of lines in the spectrum.
Explanation:
There are two types of lines in the spectrum explained below:
i) Bright lines: Bright lines occurs on the spectrum when atoms emit photons. These bright lines show the emission line spectrum.
ii) Dark Lines: Dark lines occurs on the spectrum when atoms absorb photons. These black lines show the absorption line spectrum.
Hence, by observing the color of lines it is possible to identify emission line spectrum and absorption line spectrum.
Answer:
Another metaphor that can help explain energy quantization at the atomic level is the number of teams at different stages in the Football World Cup tournament taking each stage as a given amount of energy gained by the teams at that stage as follows;
Stage 1 Group Stage
The number of teams in the group stage = 32, Energy per team = 1
Knock out stages
Round of 16
The number of teams in the round of 16 stage = 16, Energy per team = 2
Semi final
The number of teams in the semi final stage = 8, Energy per team = 4
Quarter final
The number of teams in the quarter final stage = 4, Energy per team = 8
Final
The number of teams in the semi final stage = 2, Energy per team = 16
The winning team
The number of teams that win the World Cup = 1, Energy of the team = 32
As seen as each team has a specific energy level at each stage of the world cup and there can not any energy value that is an intermediate value of the energy of the teams each at each stage, so also at the atomic level particles within the atom and therefore the atom itself can possess only specific quantum of energy values in a given level or state.

Hello There!
Kilo means thousand.
For example:
Kilometer means a thousand meters.
