Answer:
4 km/h
Explanation:
Average speed = Distance / time
Distance = 2 km
Time = 30 minutes = 0.5 hours [For units to match]
Average speed
= 2 / 0.5
= 2 x 2
= 4 km/h
Answer:
It has long been known that static pressure affects middle-ear function and conventional tympanometry uses variations in static pressure for clinical assessment of the middle ear. Middle-ear under-pressures tend to reduce the velocity magnitude more than do middle-ear over pressures.
The effect of middle-ear static pressure on the acoustic response of both structures is similar in that non-zero middle-ear static pressures generally reduce the velocity magnitude of the two membrane components in response to sound stimuli.
