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>

Explanation:
Convert the time to seconds : 5minutes × 60 = 300seconds
Acceleration = Velocity / Time
Acceleration = 20m/s / 300s
Acceleration = 0.067m/s²
Distance = Velocity × Time
Distance = 20m/s × 300seconds
Distance = 6000m
The direction in which the magnetic force is acting on the charge is upwards.
<h3>What is Magnetic force?</h3>
This is the attraction and repulsion which usually occurs during the motion of electrically charged particles.
In the magnetic field, the charge is moving to the left. Therefore the direction the magnetic force is acting on the charge is upwards which is gotten via right hand rule.

Complete question:
A person holds a 0.300 kg pomegranate at the top of a tower that is 96m high. Another person holds a 0.800 kg melon next to an open window 32m up the tower.
Calculate the gravitational potential energy of the pomegranate and melon.
Answer:
The gravitational potential energy of pomegranate is 282.24 J
The gravitational potential energy of melon is 250.88 J
Explanation:
Given;
mass of the pomegranate, m₁ = 0.3 kg
height of the pomegranate, h₁ = 96 m
mass of the melon, m₂ = 0.8 kg
height of the melon, h₂ = 32 m
The gravitational potential energy of pomegranate is calculated as;
P.E₁ = m₁gh₁
P.E₁ = 0.3 x 9.8 x 96
P.E₁ = 282.24 J
The gravitational potential energy of melon is calculated as;
P.E₂ = m₂gh₂
P.E₂ = 0.8 x 9.8 x 32
P.E₂ = 250.88 J
