Answer:
The kinetic energy is 1200 J
Explanation:
The Principle of Conservation of energy states that "energy is neither created nor destroyed, it is transformed".
This means that energy can be transformed from one form to another, but the total amount of energy always remains constant, that is, the total energy is the same before and after each transformation.
The mechanical energy of a body or a physical system is the sum of its kinetic energy and the potential energy. According to the Principle of Conservation of Energy for mechanical energy, the total mechanical energy that a body possesses is constant at every instant of time.
Since mechanical energy is equal to the sum of kinetic energy and gravitational potential energy that a body possesses, the only way to stay constant is that:
- when the kinetic energy increases the gravitational potential energy decreases,
- when gravitational potential energy increases, kinetic energy decreases.
Due to the Principle of Conservation of Energy you can say that the gravitational potential energy is converted to kinetic energy. So Gravitational potential energy at the top = kinetic energy at the bottom
<u><em>The kinetic energy is 1200 J</em></u>
Answer:
Plasma, Supersolid, Superfluid
Explanation:
I don't know if this is what you are looking for, but I have no idea what these even are.
Answer:
a) 2.33 m/s
b) 5.21 m/s
c) 882 m³
Explanation:
Using the concept of continuity equation
for flow through pipes
Where,
A = Area of cross-section
V = Velocity of fluid at the particular cross-section
given:
a) 
substituting the values in the continuity equation, we get
or
or
b) 
substituting the values in the continuity equation, we get
or
or
c) we have,
Discharge
thus from the given value, we get
Also,
Discharge
given time = 1 hour = 1 ×3600 seconds
substituting the value of discharge and time in the above equation, we get
or
volume of flow = 
Multiply 6 x 60 to get the frequency.
Hey there!
P= 3kg=3
W=m x g x d =3kg x 9 8 m/s² x 3m = 88J
Hope this helped you and solve your problem
