Answer:
the maximum is I₁ axis of rotation at the end
the minimum moment is I₂ axis of rotation at the center of mass
Explanation:
For this exercise we use the definition moment of inertia
I = ∫ r² dm
for bodies of high symmetry it is tabulated; In this case we can approximate a broomstick to a thin rod, the moment of inertia with respect to a perpendicular axis when varying are
at one end
I₁ = ⅓ mL²
in in center
I₂ =
m L²
There is another possible axis of rotation around the axis of the broom, in this case we have a solid cylinder
I₃ =
m r²
remember that the diameter of the broom is much smaller than its length, therefore this moment of inertia is very small
when examining the different moments of inertia:
the maximum is I₁ axis of rotation at the end
the minimum moment is I₂ axis of rotation at the center of mass
Yes, the first law of thermodynamics was created using the law of conservation of energy that is applied in a thermodynamic systems.the first law of thermodynamics is the change in internal energy of an
isolated system is equal to the amount of heat (Q) added to the system
minus the work (w) done by the system to the surroundings . while the law of conservation of energy states that in an isolated system that energy is constant, and energy can change its form but it cannot be created or destroyed.
The energy which is possessed by an object because of its motion is called Kinetic energy.
Example:
- Wind mills. Energy is formed by the motion of wind mills, so it is kinetic energy.

The energy which is possessed by an object because of its position is called Potential energy.

Answer:
Suppose that you have water in a metallic bowl.
Now, you start heating the water until it reaches the boiling point.
At this point the water starts transitioning from liquid phse to gas phase, now, you need to think this as the kinetic energy of the water increases to the point where it is stronger than the pressure and it can "escape" the liquid mass.
Then, if we increase the pressure, the temperature needded to escape (to change of phase) also needs to increase.
A more "thermodinamical" way to explain it, is that we can define a curve P(T) of transitions, and we also can define a curve T(P) (the inverse)
So for different values of Pressure, we should see different values of temperature for the changes of phase.
