Answer:
Hello, Your answer should be is <u><em>Auditory Nerve</em></u>
Explanation:
Because the "Auditory Nerve" bundle of nerves that carries hearing information, The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear). Its not A, because the <u>"Optic nerve"</u><em> second pairs of cranial transmitting impulses to the brain. Its not really C, Because the </em><u>"Cochlea" </u> is a <em><u>spiral cavity that is inside of the inner ear.</u></em><em> And its not D, because the </em><u><em>"Stirrup" is the stapes or stirrup is on the bone, by the middle ear of humans and mammels too.</em></u><em> So your best answer will be Auditory Nerve.</em>
Answer:
51 miles/hour
Explanation:
<em>Talia is on a road trip with some friends. in the first 2 hours, they travel 100 miles. then they hit traffic and go only 30 miles in the next hour. the last hour of their trip, they drive 75 miles. calculate the average speed of talia’s car during the trip. give your answer to the nearest whole number.</em>
<em />
<em>The average speed would be 51 miles/hour.</em>
<u>The average speed of a moving object is defined as the total distance traveled relative to the total time taken fro the journey. Mathematically, it is given as:</u>
total distance traveled/total time taken.
In this case;
Total distance traveled = 100 + 30 + 75 = 205 miles
Total time taken = 2 + 1 + 1 = 4 hours
Therefore;
Average speed = 205/4 = 51.25 miles/hour
<em>To the nearest whole number = 51 miles/hour</em>
Answer:
more than 90%
Explanation:
In the unknown liquid the buoyant force and weight relation is
![V\rho_lg=mg\\\Rightarrow V\rho_l=m](https://tex.z-dn.net/?f=V%5Crho_lg%3Dmg%5C%5C%5CRightarrow%20V%5Crho_l%3Dm)
It can be seen that if the density decreases the buoyant force decreases.
If the object is already 90% submerged in water then, if the other liquid has density less than that of water the object will be submerged more than 90%.
Answer:
4) True. The change of direction needs an unbalanced force
Explanation:
Let us propose the resolution of the problem using Newton's second law.
F = m a
As the car is spinning the acceleration is centripetal
a = v2.r
F = m v2 / r
We can see that as the velocity of a vector even if its module does not change, the change of direction requires an external force.
Now we can analyze the statement if they are true or false
1) and 3) False, even when the speed changes, the direction changes
2) False with the speed change can be determined
4) True. The change of direction needs an unbalanced force
5) False are different things. the direction is where it is going and the speed is the magnitude of the vector
Answer:
The natural frequency = 50 rad/s = 7.96 Hz
Damping ratio = 0.5
Explanation:
The natural frequency is calculated in this manner
w = √(k/m)
k = spring constant = 5 N/m
m = mass = 2 g = 0.002 kg
w = √(5/0.002) = 50 rad/s
w = 2πf
50 = 2πf
f = 50/(2π) = 7.96 Hz
Damping ratio = c/[2√(mk)] = 0.1/(2 × √(5 × 0.002)) = 0.5
