i dont understand >.<
Answer:
1. (F) Increasing the frequency variable reduces the time required.
2. (I) Intensity variable can be related the the energy expended.
3.(T) Time variable would affect the speed.
Explanation:
1. (F) increasing the frequency variable implies that the distance would be covered in lesser time. As a wave of 250Hz cover more distance than that of 200Hz.
2. (I) Intensity variable. An increase in this variable implies that more energy is expended.
3.(T) Time variable can either give the required out come or not. As increasing the time would mean that the speed has reduced, while decreasing the time means the distance would be covered quickly. If the required speed is 20m/s, then increasing it to 30m/s imples that lesser time would be recorded. If the reverse is the case, then more time would be recorded. time = distance/speed
The correct answer to the question above is The third Option: C; ultrasound imaging of the liver. The ultrasound imaging of the liver is definitely not an application of Doppler technology.
