what is the relationship between harmonics and resonance frequency in a piano
Answers
Most vibrating objects have more than one resonant frequency and those used in musical instruments typically vibrate at harmonics of the fundamental. A harmonic is defined as an integer (whole number) multiple of the fundamental frequency.
There is direct relationship between harmonics and resonance frequency.
A harmonic is a wave with a frequency that is a positive integer multiple of the frequency of the original wave whereas, resonance frequency is the frequency at which the oscillation reaches to its maximum point. The lowest resonant frequency is known as the fundamental, while on the other hand, the higher resonant frequencies are called overtones. All resonant frequencies are multiples of the fundamental, and are called harmonics. So we can conclude that there is a direct relationship between harmonics and resonance frequency.Learn more about harmonic here: https://brainly.com/question/17315536

The magnetic field of a bar magnet Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Always points from north to south, whether we look outside the magnet or inside the magnet. b Always points from south to north, whether we look outside the magnet or inside the magnet. c Points from north to south outside the magnet, but south to north inside the magnet. d Points from south to north outside the magnet, but north to south inside the magnet.
Answers
Answer:
A: Always points from north to south, whether we look outside the magnet or inside the magnet
Explanation:
When we freely suspend a bar magnet, it's magnetic field will always rest in the north to south direction due to the fact that the Earth's magnetic south pole usually lies in the direction of the geographic north while the Earth's magnetic north pole usually lies in the direction of the geographic south.
Now, we all know that in magnets, like poles will repel and unlike poles will attract. What this now means is that the magnet will always point from the north to the south direction.

a bullet of mass 120g is fired horizontally into a fixed wooden block with a speed of 20m\s. The bullet is brought to rest in a wooden block in 0.1secs by a constant resistance
calculate the;(I) magnitude of the resistance
(ii) distance moved by the bullet in the wood
Answers
Answer:
1) F = 24 N
2) Distance = 1 m
Explanation:
We are given;
Mass; m = 120 g = 0.12 kg
Initial velocity; u = 20 m/s
Final velocity; v = 0 m/s since it came to rest.
Time; t = 0.1 s
We can calculate acceleration from Newton's first equation of motion;
a = (v - u)/t
a = (0 - 20)/0.1
a = -200 m/s²
1) magnitude of the resistance will be;
F = ma
F = 0.12 × (-200)
F = -24 N
Since, we are dealing with the magnitude, we will take the absolute value. Thus, F = 24 N
2) To find the distance moved by the bullet, we know that;
Distance = Average speed × time
Thus;
Distance = ((v + u)/2) × t
Distance = ((0 + 20)/2) × 0.1
Distance = 1 m
What are the methods of plotting the magnetic field?
Answers
Answer:
The method explained below shows the plotting of magnetic field lines with the help of a small compass needle:
Procedure:
1. With the help of some board pins, fix a sheet of paper on a drawing board.
2. At point 1 as seen in the below figure, place a small compass needle. From the top of the needle, mark two pencil dots at exactly two ends of the needle.
3. Move the needle to the compass to point 2 so that one end of the needle coincides with the second pencil dot.
4. The process of moving the compass needle to points 3, 4, 5… is continued in order to get a few dots.
5. When various dots are joined, a straight line is obtained.
6. Hence, one line of magnetic field of earth is traced.
Starting from a different point, the process is repeated and another line of magnetic field is traced out. This way a few several lines of magnetic field can be traced out. Every line is required to be labelled with the help of an arrow from the south pole of the needle towards the north pole to represent the direction of the magnetic field. The figure below depicts several magnetic lines that are obtained this way.
Answer:
please give me brainlist and follow
Explanation:
Magnetic fields can be mapped out using small plotting compasses : place the plotting compass near the magnet on a piece of paper. mark the direction the compass needle points. move the plotting compass to many different positions in the magnetic field, marking the needle direction each time.

A tank containing water up to a depth of 650 mm is stationary. Find the force exerted by fluid of specific gravity 0.55 on the side of tank, width of tank is 1.5m. Ρ water = 1000 kg/m³:
Answers
Answer:
3415.91 N
Explanation:
We know pressure, P at depth, h is P = ρgh where ρ = density of fluid = specific gravity × density of water = 0.55 × 1000 kg/m³ = 550 kg/m³, g = acceleration due to gravity = 9.8 m/s² and h = depth of water = 650 mm = 0.650 m
So, P = ρgh
= 550 kg/m³ × 9.8 m/s² × 0.650 m
= 3503.5 N/m²
Now pressure P = F/A where F = force on the side of tank and A = area of side of tank = depth of water × width of tank = 0.650 m × 1.5 m = 0.975 m²
So, F = PA
= 3503.5 N/m² × 0.975 m²
= 3415.913 N
≅ 3415.91 N

Samantha is identifying different minerals by her eyes only. She will able to make a certain judgment for color, luster, and texture but not for hardness.
Hardness is the property of the material which tells about the resistance to the deformation. So, it is impossible to determine the hardness just by looking at the material. We need to perform certain tests like Brinell's hardness test, Vicker's hardness test.
