Answer:
w = w₀ / 2 the angular velocity is half the initial value.
Explanation:
We can analyze this exercise as if we added another disk to obtain a disk with twice the mass, for which if the system is two disks, the angular tidal wave is conserved
initial instant.
L₀ = I₀ w₀
final moment
L_f = I w
the moment is preserved
L₀ = L_f
I₀ w₀ = I w
the moment of inertia of a disk is
I = ½ m R²
we substitute
½ m R² w₀ = ½ (2m) R² w
w = w₀ / 2
for the case of a disk with twice the mass, the angular velocity is half the initial value.
The first experiment that was made to attempt to measure the speed of light involved detonating gunpowder by Isaac Beeckman. He declared that his experiment was inconclusive. Galileo also tried to measure the speed of light using two lanterns placed across each other. The next experiment involved planets where Ole Romer based his calculation on its movements. The final calculations were derived from different theories by different scientists including Maxwell until it ended up with the exact value for the speed of light.

Cardiorespiratory fitness improves the efficiency of the cardiovascular and the respiratory systems in delivering oxygen to the body.
Please select the best answer from the choices provided.
True
False
The correct answer to this question is True
Explanation:
The cardiorespiratory system (cardiovascular and respiratory system) includes structures and organs such as the heart, the lungs, the veins, etc. that are involved in the process of oxygenation of the body. This process can be less or more efficient depending on different factors. One of these is the cardiorespiratory fitness or the ability of the body to work effectively in terms of oxygenation during exercise or effort.
In this context, a higher cardiorespiratory fitness means the cardiorespiratory system will work more efficiently, while low fitness implies less efficient oxygenation. Additionally, this fitness can be improved through activities such as running, hiking, among others. Therefore, cardiorespiratory fitness improves efficiency in the process of oxygenation, which makes the statement true.
