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.

what is the relationship between harmonics and resonance frequency in a piano

Answers

Fundamental and Harmonics
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.

How will a ray of light traveling parallel to the principle axis of a concave mirror be reflected back

Answers

Answer:

It will be reflected to the principal focus of the concave mirror

Explanation:

This is because all rays parallel and close to the principal axis of a concave mirror get reflected to the principal focus of the mirror.

For a ray to be parallel to the mirror, it must be coming from an infinite distance.

So, using the mirror formula,

1/u + 1/v = 1/f where u = object distance from mirror, v =image distance form mirror and f =focal length of mirror.

Since u = infinite distance = ∞

1/u + 1/v = 1/f

1/∞ + 1/v = 1/f

0 + 1/v = 1/f

1/v = 1/f

v = f

So, the image is at the principal focus.

So, the ray of light parallel to the principal axis of the concave mirror is reflected to the principal focus of the concave mirror.

What is the quality of the sound of an ambulance's siren when it moves toward a stationary hearer? What is the quality of the sound of an ambulance's siren when it moves away from a stationary hearer?

Answers

Answer:

A) As the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch

B) As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.

Explanation:

From Doppler effect, the closer the source of sound gets to the observer, the higher the frequency and in turn the higher the pitch.

Meanwhile, the farther a source goes from an observer, the lower the frequency of the sound and also the lower the pitch.

Thus, as the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch.

As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.

Answer:

a. The quality of the sound would have a high pitch and thus be loud.

b. The quality of the sound would have a low pitch and thus would have a lower volume than the sound from the source.

Explanation:

Using the formula for Doppler shift f' = (v ± v')f/(v ± v") where v = speed of sound in air, v'= speed of hearer = 0 m/s (since he is stationary), v" = speed of ambulance and f = frequency of sound from ambulance

So, f' = (v ± v')f/(v ± v")

f' = (v ± 0)f/(v ± v")

f' = vf/(v ± v")

a. What is the quality of the sound of an ambulance's siren when it moves toward a stationary hearer?

Since the source (ambulance) moves towards the detector, (hearer), we would get an upwards shift in frequency. (Since our denominator has to be a minimum, so we use the minus sign for v"). So, the quality of the sound would have a high pitch and thus be loud.

b. What is the quality of the sound of an ambulance's siren when it moves away from a stationary hearer?

Since the source (ambulance) moves away the detector, (hearer), we would get a downward shift in frequency. (Since our denominator has to be a maximum, so we use the plus sign for v"). So, the quality of the sound would have a low pitch and thus would have a lower volume than the sound from the source.

Given

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.

Answers

Answer:

2 m/s²

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 2 m/s

Final velocity (v) = 6 m/s

Time (t) = 2 s

Acceleration (a) =?

The acceleration of the person can be obtained as follow:

v = u + at

6 = 2 + (a×2)

6 = 2 + 2a

Collect like terms

6 – 2 = 2a

4 = 2a

Divide both side by 2

a = 4 / 2

a = 2 m/s²

Therefore, the acceleration of the person is 2 m/s²

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

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

A ball starts from rest and accelerates at a constant rate of 1.0m/s to a final velocity of
5.5m/s. How long did it take for this ball to reach its final velocity?

Answers

Answer:

Time taken to reach final velocity = 5.5 second

Explanation:

Given:

Initial velocity (Starting from rest)(u) = 0 m/s

Acceleration of ball (a) = 1 m/s²

Final velocity (v) = 5.5 m/s

Find:

Time taken to reach final velocity

Computation:

Using first equation of motion;

v = u + at

where,

v = final velocity

u = initial velocity

a = acceleration

t = time taken

5.5 = 0 + (1)(t)

5.5 = t

Time taken to reach final velocity = 5.5 second
