Final answer:
The speed of a pulse can be assessed by multiplying its speed with the time taken. For a pulse at 2.5 m/s over 6 seconds, it covers 15 meters. The feeling of a pulse is the arterial expansion and recoiling from blood flow; a ten second count should be six times less than a one minute count.
Step-by-step explanation:
To assess the speed of the pulse, we need to use the distance travelled by the pulse and the time taken for that travel. If we know a pulse has a speed of 2.5 m/s, and we want to find out how far it will have travelled in 6 seconds, we simply multiply the speed by the time. The calculation would be 2.5 m/s × 6 s = 15 meters. Therefore, the pulse would have travelled 15 meters in 6 seconds.
When looking at various scenarios where a pulse is traveling, such as the example of a pulse moving at 1 m/s and having to sketch the resulting waveforms after 1 second, 2 seconds, and so on, we follow the same principle. For each second, the pulse travels 1 meter. After 1 second, it will be 1 meter away from the starting point, after 2 seconds, 2 meters away, and so on, based on the given speed of the pulse.
In the case of feeling your pulse rate, what you are actually feeling is the expansion and recoiling of your arteries as blood is pumped through them by your heart. If you measure your pulse for 10 seconds and then for 1 minute, you should ideally see a factor of 6 difference because 1 minute consists of 60 seconds, which is six times 10 seconds.
