A new band sensation is playing a concert and recording it for a live album to be released this summer. The band asks the sound mixer if he can autotune
the singer who has a habit of singing slightly lower than the note.
What would the mixer need to do to the sound wave? How would it affect the characteristics of the wave?
Answers
The sound mixer will need to increase the amplitude of the sound wave produced by the singer which will increase the loudness of the sound.
Amplitude of sound waveThe amplitude of a sound wave is the maximum vertical displacement of the sound wave.
The sound mixer will need to increase the amplitude of the sound wave produced by the singer.
The increase in the amplitude of the sound wave produced by the lower tune singer will result in increased loudness of the sound.
Thus, the sound mixer will need to increase the amplitude of the sound wave produced by the singer which will increase the loudness of the sound.

The planet Earth orbits the sun with a period of one year. In this problem, you may assume the radius of the Earth's orbit is 1.50 × 10^8 km. what is the average velocity of relative to the sun over the period of one year in meters per second.
Answers
ANSWER:
The velocity is 29884.89 m/s
The avergae velocity is 0 m/s
STEP-BY-STEP EXPLANATION:
We know that the speed is given by the distance for a certain time (in this case a year).
We know that the distance traveled would be equal to the circumference of the circle formed, which can be calculated by means of the radius.
We have the following equivalences:
1 km = 1000 m
1 year = 365 days
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
Therefore, we calculate the velocity as follows:
\(\begin{gathered} v=\frac{d}{t} \\ d=2\cdot\pi\cdot r=2\cdot3.1415\cdot1.5\cdot10^8\operatorname{km}\cdot\frac{1000\text{ m}}{1\text{ km}}=942450000000 \\ t=1\text{ yr}\times\frac{365\text{ days}}{1\text{ yr}}\times\frac{24\text{ hr}}{1\text{ day}}\times\frac{60\text{ min}}{1\text{ hr}}\times\frac{60\text{ sec}}{1\text{ min}}=31536000 \\ \text{ replacing} \\ v=\frac{942450000000}{31536000} \\ v=29884.89\text{ m/s } \end{gathered}\)Now, since the initial and final position are the same, we would have:

Water flows at a speed of 13 m/s through a pipe that has a diameter of 1.2 m. What is the
diameter of the smaller end of the pipe that the water comes out with a speed of 30 m/s?
Answers
The diameter of the smaller end of the pipe is approximately 0.78 meters.
To determine the diameter of the smaller end of the pipe, we can use the principle of conservation of mass. According to this principle, the mass flow rate of water should remain constant throughout the pipe.
The mass flow rate is given by the equation:
Mass flow rate = density of water * cross-sectional area * velocity
Since the density of the water remains constant, we can write:
Cross-sectional area1 * velocity1 = Cross-sectional area2 * velocity2
Given that the velocity1 is 13 m/s, the diameter1 is 1.2 m, and the velocity2 is 30 m/s, we can solve for the diameter2 using the equation:
(pi * (diameter1/2)^2) * velocity1 = (pi * (diameter2/2)^2) * velocity2
Simplifying the equation:
(1.2/2)^2 * 13 = (diameter2/2)^2 * 30
Calculating the equation:
(0.6)^2 * 13 = (diameter2/2)^2 * 30
0.36 * 13 = (diameter2/2)^2 * 30
4.68 = (diameter2/2)^2 * 30
Dividing both sides by 30:
0.156 = (diameter2/2)^2
Taking the square root of both sides:
0.39 = diameter2/2
Multiplying both sides by 2:
0.78 = diameter2

Assume you are going to race the three objects (hollow sphere, disk and ring used in Experiment 8.2) by releasing them from rest at the top of an inclined plane.Which object do you expect to reach the bottom of the inclined plan first? Why?
Answers
Answer:
a. The disk
b. Because it has the smallest rotational inertia
Explanation:
a. Which object do you expect to reach the bottom of the inclined plan first?
I would expect the disk to reach the bottom first.
b. Why?
This is because the disk has the smallest rotational inertia.
The rotational inertial of the hollow sphere, disk and ring are 2/3MR², 1/2MR² and MR² respectively.
Since the three objects are rolling from the same height, they have the same mechanical energy.
But, since the disk has the smallest rotational inertia, it would have the smallest rotational kinetic energy and largest translational kinetic energy. The disk's smaller rotational kinetic energy will cause to rotate less but translate more than the other objects and thus reach the bottom first.
The object which is expected to reach the bottom of the inclined plan first is the disk, as it has the lowest rotational inertia.
What is a moment of inertia?Moment of inertia is the force which acts in the opposite direction of the force of angular acceleration acting on the body.
There are three objects, hollow sphere, disk and ring.
The moment of inertia of the hollow sphere object is given as,\(I=\dfrac{2}{3}mr^2\)
The moment of inertia of the ring is,\(I=mr^2\)
The moment of inertia of the disk is,\(I=\dfrac{1}{2}mr^2\)Here, (m) is the mass and (r) is the radius of the object.
These three objects are going to race by releasing from rest at the top of an inclined plane to the bottom of the plane.
As moment of inertia is the force which acts in the opposite direction of the force of angular acceleration acting on the body.
Thus the less the value of inertia will result in less the time required to reach at the bottom of the inclined plane.
Hence, the object which is expected to reach the bottom of the inclined plan first is the disk, as it has the lowest rotational inertia.

The magnitude of the force that the 6.3 kg block exerts on the 4.3 kg block is approximately 41.9 N
Explanation:
Forces on block 4.3 kg are:
63N to the right and R21 (contact force from the 6.3 kg block) to the left
Net force on 4.3 kg block is: 63 N - R21
Forces on the 6.3 kg block are:
R12 to the right (contact force from the 4.3 kg block) and 11 N to the left.
So net force on the 6.3 kg block is: R12 - 11 N
According to the action-reaction principle the contact forces R21 and R12 must be equal in magnitude (let's call them simply "R").
Then, since the blocks are moving with the SAME acceleration, we equal their accelerations:
a1 = (63 N - R)/4.3 = (R - 11 N)/6.3 = a2
solve for R by cross multiplication
6.3 (63 - R) = 4.3 (R - 11)
396.9 - 6.3 R = 4.3 R - 47.3
369.9 + 47.3 = 10.6 R
444.2 = 10.6 R
R = 444.2 / 10.6
R = 41.90 N

from the near (west) edge of the intersection at which the nose of the red car can begin its motion if it is to enter the intersection after the blue car has entirely left the intersection? (d) If the red car begins its motion at the position given by the answer to part (c), with what speed does it enter the intersection?
Answers
The distance of the blue car from the edge of the intersection, when it stops, is 35.9 m, the time interval of the blue car within the boundaries of the intersection is 4.04 s, the minimum distance is 45.8 m, and the speed of the car is 22.6 m/s.
From the given,
A) the distance of the blue car from the south edge of the intersection when it stops =?
The width of the intersection = 28m
Acceleration = -2.10 m/s²
time interval = 3.10 s
By using the equation
x = x₀ + v₀t + 1/2 (at²)
28 = 0 + v₀(3.10) + 1/2 (-2.10 ×(3.10)²)
v₀ = 12.3 m/s
v² = v₀² + 2a (x-x₀)
(x-x₀) = Δx = v²-v₀² / 2a
Δx = 35. 9m
B) the time interval=?
distance covered by the blue car = 4.52 + 28 = 32.52 m
By using the relation,
x = x₀ + v₀t + 1/2 (at²)
32.52 = 0 + (12.3)t + 1/2 (-2.10)t²
-1.05t²+12.3t-32.52 = 0
This is the quadratic equation. By solving it, time t= 4.04s,7.66s. The desired time is t = 4.04 s, and the tail of the blue car leaves the intersection.
C) the minimum distance is=?
x = x₀ + v₀t + 1/2 (at²)

x-component = 35(0.7071)
x-component = 24.749m/s
y-component = 35sin45
y-component = 35(0.7071)
y-component = 24.749m/s
Hence its x and y component is 24.749m/s
