Answer:
The displacement, the time and the direction
Explanation:
The velocity of an object is defined as:
where
d is the displacement, which is a vector describing the change in position of the object
t is the time in which the displacement takes place
Since d (the displacement) is a vector, velocity is a vector as well: this means that it also has a direction, which corresponds to the direction of the displacement.
The magnitude of the velocity, insteand, is called speed.
The frequency of the nth-harmonic is an integer multiple of the fundamental frequency of the string:
where
is the fundamental frequency.
Here, we know the frequency of the 4th harmonic
, therefore we can use it to find the fundamental frequency and the following overtones:
Since the hearing range of human ear goes from 20 Hz to 20 kHz, it means that only the first harmonic of 11 kHz will be audible to humans.
Answer:
<em><u>Hypothesis #2 If an earthworm is exposed to a strong odor, then it will back away from the odor because it will think that the odor is a sign of danger. ... Second, you will test earthworms' response to dry conditions by providing both a dry surface and a moist surface for the earthworms to crawl on.</u></em>
