Answer:
29.5 m/s
Explanation:
Volumetric flowrate = (average velocity of flow) × (cross sectional area)
Volumetric flowrate = 0.111 liters/s = 0.000111 m³/s
Cross sectional Area of flow = πr²
Diameter = 0.00579 m,
Radius, r = d/2 = 0.002895 m
A = π(0.002895)² = 0.0000037629 m²
Velocity of flow = (volumetric flow rate)/(cross sectional Area of flow)
v = 0.000111/0.0000037629
v = 29.5 m/s
Given Information:
diameter of the nozzle = d = 5.79 mm = 0.00579 m
flow rate = 0.111 liters/sec
Required Information:
Velocity = v = ?
Answer:
Velocity = 4.21 m/s
Explanation:
As we know flow rate is given by
Flow rate = Velocity*Area of nozzle
Where
Area of nozzle = πr²
where
r = d/2
r = 0.00579/2
r = 0.002895 m
Area of nozzle = πr²
Area of nozzle = π(0.002895)²
Area of nozzle = 2.6329x10⁻⁵ m²
Velocity = Flow rate/area of nozzle
Divide the litters/s by 1000 to convert into m³/s
0.111/1000 = 1.11x10⁻⁴ m³/s
Velocity = 1.11x10⁻⁴/2.6329x10⁻⁵
Velocity = 4.21 m/s
Therefore, the water exit the nozzle at a speed of 4.21 m/s

Explanation:
solution below
The quantum of energy for one atomic oscillator in tungsten, given the effective interatomic spring stiffness of 360 N/m, the mass of one tungsten atom as 3.074 x 10^-25 kg, and the reduced Planck's constant of 1.0546 x 10^-34 J · s, can be calculated to be approximately 1.33 x 10^-21 J.
To calculate the quantum of energy for one atomic oscillator in tungsten, we will consider the model of an atom being connected to two springs, both having an effective interatomic spring stiffness of four times the given value (90 N/m). This value thus becomes 360 N/m.
One mole of tungsten has a mass of 0.185 kg, thus the mass of one atom can be determined by dividing this value by Avogadro's number (6.0221 x 10^23 molecules/mole), which gives approximately 3.074 x 10^-25 kg.
The quantum of energy, or the energy of one quantum (the smallest possible energy increment), is given by the formula E = ħω, where ħ is the reduced Planck's constant (1.0546 x 10^-34 J · s) and ω is the angular frequency, given by sqrt(k/m), where k is the spring constant and m is the mass.
Substituting the known values into these equations gives ω= sqrt((360)/(3.074 x 10^-25)) and E= (1.0546 x 10^-34) x sqrt((360)/(3.074 x 10^-25)), which results in a quantum of energy of approximately 1.33 x 10^-21 J.

(a) 24.6 Nm
The torque produced by the net thrust about the center of the circle is given by:
where
F is the magnitude of the thrust
r is the radius of the wire
Here we have
F = 0.795 N
r = 30.9 m
Therefore, the torque produced is
(b)
The equivalent of Newton's second law for a rotational motion is
where

I is the moment of inertia
is the angular acceleration
If we consider the airplane as a point mass with mass m = 0.741 kg, then its moment of inertia is
And so we can solve the previous equation to find the angular acceleration:
(c)
The linear acceleration (tangential acceleration) in a rotational motion is given by
where in this problem we have
is the angular acceleration
r = 30.9 m is the radius
Substituting the values, we find

Explanation:
Responsibilities of citizens are those things citizens are to take care of.
While obligations are those things that are compulsory for the citizens to observe and adhere to.
Why are certain things obligations of citizenship instead of responsibilities?
1.) Because of law and order of the community. It is mandatory for all citizens to obey the law of the land.
2.) Because of the progress and peaceful coexistence of the citizens in the community.
3.) Because of the protection of constitution of the land
4.) To support and defend the constitution
5.) To maintain orderliness and eschew violence.
