Answer:
Explanation:
Given,
After two revolutions, angular speed = 0.5 rev/s
Angular speed after 8 revolution = ?
Using equation of circular motion
Now, Angular speed after 8 revolution
Hence, the angular speed after 8 revolution is equal to 1 rad/s.

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.
The answer is : Low frequency sounds
place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along basilar membrane, which is very sensitive to low frequency sound
The change from broken white lines to a solid line on the pavement markings of traffic signifies that overtaking from any side is not allowed or prohibited. The broken line signifies that you can overtake when safe.
Any time that the sign (+ or -) of the acceleration<span> is the same as the sign of the </span>velocity<span>, the object will speed up. If the signs are opposite, the object will slow down. </span>Acceleration<span> is a vector quantity. When either </span>velocity<span> or direction changes, there is </span>acceleration<span> (or deceleration).</span>
