The cochlea detects sound and is tonotopically organized
The cochlea is the auditory sense organ within the inner ear that is responsible for hearing. The cochlea is a coiled, fluid-filled tube that is split into three chambers by two membranes, Reissner's membrane and the basilar membrane
Answer:
The magnitude of the sum of A and B is 27.51 N.
Explanation:
We can separate the x- and y-components of the vectors, then sum these components separately. Afterwards, we can calculate the magnitude of the sum.
On the other hand, for the vector B:
The sum of the components in the x-direction is equal to 22.85 N.
The sum of the components in the y-direction is equal to 15.32 N.
Finally, the magnitude of the sum vector C is
Answer:
Explanation:
We need to supply 5 Nm to the bolt.
If we have a force of 25 N in the direction (2*i - 3*j), the torque is related to the length of the wrench.
T = F * d
d = T / F
d = 5 / 25 = 0.2 m
Assuming the wrench is perpendicular to the force.
The vector of the force is:
This is a countr-clockwise direction. If the bolt is right handed (most are) we are tightening it.
Answer:
2.5 Hz
Explanation:
3.0m/s / 1.2 m=2.5 1/s=2/5 Hz
Such questions are not at all difficult... You must have patience as well good at trigonometry.. rest it depends whether you are cleared with concepts or not. Practice such questions daily you'll be master then. Hope you are able to see my solution :)
