Answer:
Explanation: Peripherial arterial disease is a blood circulation disorder which occurs when the blood vessels outside the heart and brain to block or spasm. This is as a result of the pulse decreasing rather than increasing in amplitude.
Answer:
Explanation:
We use the following rotational kinematic equation to calculate the angular acceleration of the rod:
Here is the final angular speed, is the initial angular speed and is the angular acceleration. The rod starts rotating from rest ():
Recall that the angular speed is defined in function of the tangential speed (v) and the radius (r) of the circular motion:
In this case the radius is given by . Replacing (2) in (1):
Answer:
The second is defined in terms of a cesium-atom laser and its vibrations.
Explanation:
However, real time is defined in terms of the mean solar day, and it is thus necessary to add leap seconds to the atomic clocks to keep them in line with the astronomical clocks.
Hope this helped :)
