In one to two sentences, describe the relationship between harmonics and resonance frequency in a piano?
The harmonic frequency is the frequency of the harmonic motion. Whereas the resonance frequency is the frequency at which the oscillation achieves its highest point.
What is resonance frequency?Mechanical systems and charged particles all have a frequency that they vibrate at. this frequency is referred to as the resonance frequency or natural frequency.
When the matching vibrations of another item enhance the amplitude of an object's oscillations, this is known as resonance.
A harmonic is a wave with a frequency that is a positive integer multiple of the original wave's frequency.
Whereas the resonance frequency is the frequency at which the oscillation achieves its highest point.
The fundamental frequency is the lowest resonant frequency, while the overtones are the higher resonant frequencies. Harmonics are all resonant frequencies that are multiples of the fundamental.
Hence we may deduce that harmonics and resonance frequency have a direct relationship.

a graph for horizontal position vs gravitational potential energy represents which of the following
(a) represent the slope of a track
(b) represent opposite of slope of track
(c) a linear relationship
Answer:
this may not be what you're looking for but here you go
Explanation:
A horizontal line means the object is not changing its position - it is not moving, it is at rest. A downward sloping line means the object is returning to the start. Speed-Time graphs are also called Velocity Time graphs. Speed-Time graphs look much like Distance-Time graphs.

A tuning fork is struck and produces a sound. The wavelength of this
sound is 2.5 m and the period of this sound is 0.25 s. Find the
frequency of the sound wave and the speed of the wave.
Answer:
Speed= 10meters per second, Frequency = 4hz
Explanation:
First we need to find the frequency of the wave. The formula for frequency is: f (frequency) = 1 / T (period). This means we need to convert the period into seconds and then use it as a denominator with one on the numerator.
Since the period is 0.25,
1/0.25= 4hz
Now, we just need to multiply the frequency with the wavelength
4hzx2.5= 10
= 10 meters per second

Which form of electromagnetic radiation produces the warmth one feels when standing in front of a campfire?.
A disk-shaped platform has a known rotational inertia. The platform is mounted on a fixed axle and rotates in a horizontal plane, as shown above. A student wishes to determine the frictional torque exerted on the platform by the axle as the platform rotates. The student has access to equipment that would usually be found in a school physics laboratory.
The quantities that can be measured from the disk-shaped platform include mass, radius for moment of inertia, and rotational frequency for omega.
What is Inertia?It should be noted that inertia simply means the property of all matter by which they tend to remain in constant and uniform motion unless they're acted by an external force.
In this case, the quantities that can be measured from the disk-shaped platform include mass, radius for moment of inertia, and rotational frequency for omega.

17. An ambulance at rest blows a siren of frequency 700 Hz. A vertical reflecting board
which is moving at constant velocity 4 ms¹ towards the ambulance. How many beats
per 5 seconds can be heard by the driver in the ambulance?
(The speed of sound is 350 ms ¹)
Answer:
In this case the board is moving towards the observer so the board will receive the frequency as a moving observer
The board then emits the sound received and becomes a moving source according to the driver in the ambulance
f' = f (V + Vo) / V where V is the speed of sound and f' is the frequency received by the moving board
Now the board becomes a moving source and
f' = f (V / (V - Vs) and V is again the speed of sound
Combining these equations we get
f = (V + Vo) / (V - Vs) = 700 (350 + 4) / (350 - 4) = 716 / s
The driver would hear 16 beats / sec
Note: one can do these separately
f' = 700 * (350 + 4) / 350 = 708 frequency received for moving observer
f' = 708 * 350 / (350 - 4) = 716 / sec moving source stationary observer
Every 5 sec one would hear 5 * 16 = 80 beats

Following are the ways that Venus does not follow the patterns of the other inner planets because Venus lacks life and water oceans, like does Earth.
What are inner planet?Mercury, Mars , Earth,and Venus and are known as inner planets because their surfaces are compact and rocky, similar to Earth's terra firma.
Venus and the other inner planet are pretty different as well. Following are the ways that Venus does not follow the patterns of the other inner planets are;
1. Venus has an atmosphere that is nearly 100 times thicker than Celestial bodies with extremely heated surface temperatures.
2. Venus lacks life and water oceans, like does Earth.

Two objects are placed on a scale so that it balances. One object weighs 5 N and is placed 0.5 m from the fulcrum of the scale. The other object is placed 1 m from the fulcrum. How heavy is the other object?
The weight of the other object placed 1 m from the fulcrum that balances the other object is 2.5 N.
Principle of moment
The weight of the second object is determined by applying principle of moment as shown below;
take moment about the pivot,
sum of clockwise moment = sum of anticlockwise moment
F₁r₁ = F₂r₂
5 x 0.5 = F₂ x 1
2.5 N = F₂
Thus, the weight of the other object placed 1 m from the fulcrum that balances the other object is 2.5 N.

State 'True' or 'False'. Rewrite the false statements correctly.
1.The body at terminal velocity will have less weight than the drag force.
2.The line of gravity is always within the base of support of the body in stable equilibrium
3.The force that accelerates a falling body is the force of friction.
Answer:
1. False
Corrected statement: The body at terminal velocity will have equal weight to the drag force.
2. True
3. False
Corrected Statement: The force that accelerated a falling body is the force of gravity.
Explanation:
1. This statement is false. Terminal velocity occurs when the magnitude of the drag force is equal to the magnitude of the force of gravity. This causes zero net force, meaning zero accleration and the object is at its maximim (terminal) velocity.
2. True - if a body is in stable equilibrium, the line of grvaity must be within the base of support.
3. A falling body towards the center of a planet is caused by the force of gravity.
