The blending of the fundamental tone with overtones produces the __?__of an instrument.

Answers

Answer:

The blending of the fundamental tone with overtones produces the Sound Quality of Musical Instruments of an instrument.

The blending of the fundamental tone with overtones produces the sound quality of Musical Instruments  of an instrument.

The tone of a sound wave determines the timbre, also known as timber, of the auditory impressions it creates. The wave structure of a sound, which varies with the amount of overtones, or harmonics, present, their frequencies, and their relative intensities, determines the timbre of the sound.Resonance is a common technique used by musical instruments to enhance sound waves and increase volume. When an object vibrates in response to sound waves of a particular frequency, this is known as resonance.

What are tones and overtones?Aside from a simple sine wave, the fundamental tone and numerous additional tones of various frequencies make up the waveforms of all sounds. Overtones or harmonics are non-fundamental tones that are whole-number multiples of the fundamental tone.

A student decides to give his bicycle a tune up. He flips it upside down (so there's no friction with the ground) and applies a force of 34 N over 0.6 seconds to the pedal, which has a length of 16.5 cm. If the back wheel has a radius of 33.0 cm and moment of inertia of 1200 kg cm^2, what is the tangential velocity of the rim of the back wheel in m/s

Answers

Answer:

[tex]V=9.2565m/s[/tex]

Explanation:

From the question we are told that:

Force [tex]F = 34 N[/tex]  

Time [tex]t = 0.6 s[/tex]

Length of pedal [tex]l_p=16.5cm \approx0.165m[/tex]

Radius of wheel [tex]r = 33 cm = 0.33 m[/tex]

Moment of inertia, [tex]I = 1200 kgcm2 = 0.12 kg.m2[/tex]

Generally the equation for Torque on pedal [tex]\mu[/tex] is mathematically given by

[tex]\mu=F*L\\\mu=34*0.165[/tex]

[tex]\mu=5.61N.m[/tex]

Generally the equation for  angular acceleration [tex]\alpha[/tex] is mathematically given by

 [tex]\alpha=\frac{\mu}{l}[/tex]

 [tex]\alpha=\frac{5.61}{0.12}[/tex]

 [tex]\alpha=46.75[/tex]

Therefore Angular speed is \omega

[tex]\omega=\alpha*t[/tex]

[tex]\omega=(46.75)*(0.6)[/tex]

[tex]\omega=28.05rad/s[/tex]

Generally the equation for  Tangential velocity V is mathematically given by

[tex]V=r\omega[/tex]

[tex]V=(0.33)(28.05)[/tex]

[tex]V=9.2565m/s[/tex]

A lawnmower is pushed with a force of 72 Newtons at an angle of 40 degrees from the horizontal. How much work is done to the mower if it moves 740 meters?

Answers

The work done to the mower is the product of the external force applied on the object and the distance covered by the object which is equal to 40,811 Joules.

What is Work done?

Work done on an object can be defined as the product of external force applied on the object and the distance over which the force is being applied on the object. Work is done on an object when a force is applied to an object and the object is moved through certain distance.

From this we can see that the horizontal component of the force:

X-Component (horizontal component):

cos(θ) = x/F

Then,

X= F cos(θ).…..(1)

Now putting the values of F and θ in equation (1) we get,

X = 72 N × cos(40)

X = 72 N × 0.766

X= 55.15 N this is the x-component force

The work done to the mower is:

W = F × d

W = 55.15 × 740

W = 40,811 Joules

The work done to the mower is 40811 Joules.

Answers

It is a “new moon” (the Moon is totally dark in the sky). The gravitational force between the Earth and the Moon is:

2.9 x 10^20 N3.5 x 10^22 N3.5 x 10^22 N

What is gravitational force?

Generally, The gravitational force between two objects is given by the equation:

force = G * (mass1 * mass2) / distance^2

Where G is the gravitational constant (6.67 x 10^-11 N*(m/kg)^2), mass1 and mass2 are the masses of the two objects, and distance is the distance between the two objects.

The mass of the Earth is 5.972 x 10^24 kg, the mass of the Moon is 7.347 x 10^22 kg, and the mass of the Sun is 1.989 x 10^30 kg. The average distance between the Earth and the Moon is 384,400 km, and the average distance between the Earth and the Sun is 149.6 million km.

The gravitational force between the Earth and the Moon is:

force = (G * (mass of Earth) * (mass of Moon)) / (distance between Earth and Moon)^2 force

= (6.67 x 10^-11 N*(m/kg)^2) * (5.972 x 10^24 kg) * (7.347 x 10^22 kg) / (384400 x 10^3 m)^2 force

= 2.9 x 10^20 N

The gravitational force between the Earth and the Sun is:

force = (G * (mass of Earth) * (mass of Sun)) / (distance between Earth and Sun)^2 force

= (6.67 x 10^-11 N*(m/kg)^2) * (5.972 x 10^24 kg) * (1.989 x 10^30 kg) / (149.6 x 10^9 m)^2 force

= 3.5 x 10^22 N

To find the net gravitational force on the Earth from the Sun and Moon combined, we add the two forces we found above.

Net force = 2.9 x 10^20 N + 3.5 x 10^22 N

= 3.5 x 10^22 N

When it is a Full Moon the distance is the same 384,400 km

A horizontal spring mass system is to be constructed. A spring which has a spring constant of 3 kg/s2 will be used. The system should be designed so that when it is released and vibrating freely (there is no forcing) the amplitude of its vibrations will decay like ????−0.4t, and it should oscillate with a period of 4 seconds.
(Although the motion is oscillatory it is not strictly periodic because the amplitude decays exponentially. In this context "period" refers to the period of the sine and/or cosine functions that create the oscillations in the motion.)
Based on these constraints determine the mass of the object, ????(kg), to be used, and also determine the value of the friction coefficient, ???? (kg/s).
????: kg
b: kg/s

Answers

Answer:

a) 1.1418 kg

b) 0.9135 kg/s

Explanation:

Given data :

spring constant ( k ) = 3 kg/s^2

amplitude of vibrations will decay like :  

The mass of the object will be 1.418 kg and the value of the friction coefficient, b is 0.9135 kg/s.

What is  Periodic motion?

In physics, a periodic motion is a movement that repeats at regular intervals. A swing in motion, a rocking chair, a bouncing ball, a tuning fork vibrating, the Earth orbiting the Sun, and a water wave are all examples of periodic motion. The time interval for repetition, or cycle, of the motion, is referred to in each case as a period, and the frequency is the number of periods per unit of time.

According to the question, the given values are :

Spring constant, k = 3 kg/s²,

Time, T₁ = 4 sec

r = 0.4

The formula for damped oscillation is : [tex]e^-^r^t[/tex]

r = b / 2 m

w₁ = [tex]\sqrt{w_0^2-r^2}[/tex]

T₁ = 2π / w₁

= 2 π /        [tex]\sqrt{w_0^2-r^2}[/tex]

w₀ = [tex]\sqrt{4 \pi^2/T_1 +r^2}[/tex]

[tex]\sqrt{k/m}[/tex] = [tex]\sqrt{4 \pi^2/T_1 +r^2}[/tex]

M = k / [tex]{4 \pi^2/T_1 +r^2}[/tex]

M = 3/ (4π/4² +(0.4)²)

M = 1.1418 kg

b = 2 Mr = 2 × 1.1418 × 0.4

b = 0.9135 kg/s

Hence, the mass of the object is 1.1418 kg and the friction coefficient is 0.9135 kg/s.

In a cloud chamber experiment, a proton enters a uniform 0.260 T magnetic field directed perpendicular to its motion. You measure the proton's path on a photograph and find that it follows a circular arc of radius 6.42 cm.

Required:
How fast was the proton moving?

Answers

Answer:

the proton speed of the proton was 1.6 × 10⁶ m/s

Explanation:

Given the data in the question;

Radius r = 6.42 cm = 0.0642 m

magnetic field B = 0.260 T

we know that; charge of proton q = 1.602 × 10⁻¹⁹ C

And mass of proton m = 1.672 × 10⁻²⁷ kg

we know that; Magnetic Force F = qvBsinθ

where q is the charge of proton, v is velocity, B is the magnetic field and θ is  angle ( 90° )

Also the Centripetal force experienced by the particle is;

F = mv² / r

where r is radius, m is mass of proton and v is velocity

hence;

qvBsinθ = mv² / r

we solve for v

rqvBsinθ = mv²

divide both sides by mv

rqvBsinθ / mv = mv² / mv

rqBsinθ / m = v

so we substitute

v = [ 0.0642 m × (1.602 × 10⁻¹⁹ C) × 0.260 T × sin(90°) ] /  1.67 × 10⁻²⁷ kg

v = 2.6740584 × 10⁻²¹ / 1.672 × 10⁻²⁷

v = 1.6 × 10⁶ m/s

Therefore, the proton speed of the proton was 1.6 × 10⁶ m/s

b. the force at the left-hand end.

Answers

Answer:

[tex]F_l=1140N[/tex]

Explanation:

From the question we are told that:

Length[tex]l=3.00m[/tex]

Support distance [tex]d=1.00m[/tex]

Weight of diver [tex]W_d=500N[/tex]

Weight of board [tex]W_b=280N[/tex]

Generally the equation for Total Torque is mathematically given by

 [tex]F_T=W_d-W_b[/tex]

 [tex]F_T=F_d-f_b[/tex]

 [tex]F_T=-280-500[/tex]

 [tex]F_T=-780[/tex]

 [tex]F_T=780[/tex]

Since we consider the horizontal axis

 [tex]\sum Y=0[/tex]

 [tex]Fs-(\frac{1}{2}l*w_b)-(l-w_d)[/tex]

 [tex]Fs-1.5*280-3*300=0[/tex]

 [tex]F_s=1920N[/tex]

Therefore  the force at the support point  1.00m from the force at the left-hand

 [tex]F_l=F_s-F_l[/tex]

 [tex]F_l=1920-780[/tex]
