Answer:

1.wavelength

Explanation:

2. Frequency

3.Speed

4.Amplitude

Answer:

Wave is the propagation of disturbance from one place to another in an organised manner. Waves can be mechanical waves or non-mechanical waves. Mechanical waves like sound waves, require a medium to propagate. While electromagnetic waves are non-mechanical waves that do not require a medium and can travel through a vacuum.

If the particles of the medium move in a direction perpendicular to the wave propagation then the waves are called transverse waves. Longitudinal waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation.

5 Important Properties of Waves

The main properties of waves are as follows –

Property 1:Amplitude

The maximum displacement of the wave from the mean position is called the amplitude of the wave. It is the maximum height from the centre line to the crest or the trough. The crest is the highest point of the wave and the trough is the lowest point of the wave. Amplitude is measured in metres.

Property 2: Frequency

The number of vibrations passing a fixed point in a given amount of time is called frequency. The unit of frequency is Hertz.

Property 3: Wavelength

Wavelength is the distance between two identical points (adjacent crests or troughs). It is measured in metres. Frequency and wavelength are inversely proportional to each other.

Property 4: Time Period

The time taken by a complete wave to pass through a particular point is called the time period. The time period is measured in seconds. The time period is the reciprocal of the frequency.

Property 5: Speed

For a wave, speed is the distance travelled by a particular point on the wave in the given interval of time. Speed is measured in metres per second.

The mathematical representation of a sine wave with a peak amplitude of 5 and a frequency of 500 Hz is y(t) = 5sin(2π500t). The corresponding period for a frequency of 18 Hz is 0.0556 seconds (s). The corresponding period for a frequency of 20 MHz is 0.00000005 seconds (s).

(a) The mathematical representation of a sine wave with a peak amplitude of 5 and a frequency of 500 Hz is:

y(t) = 5sin(2π500t)

(b) To calculate the corresponding period for a frequency of 18 Hz:

Period (T) = 1 / Frequency

T = 1 / 18 Hz = 0.0556 seconds (s)

Converting to milliseconds: T = 0.0556 s * 1000 ms/s = 55.6 milliseconds (ms)

Converting to microseconds: T = 0.0556 s * 1000000 μs/s = 55600 microseconds (μs)

(c) To calculate the corresponding period for a frequency of 20 MHz:

Period (T) = 1 / Frequency

T = 1 / 20,000,000 Hz = 0.00000005 seconds (s)

Converting to milliseconds: T = 0.00000005 s * 1000 ms/s = 0.00005 milliseconds (ms)

Converting to microseconds: T = 0.00000005 s * 1000000 μs/s = 0.05 microseconds (μs)

(d) To calculate the corresponding period for a frequency of 4 kHz:

Period (T) = 1 / Frequency

T = 1 / 4,000 Hz = 0.00025 seconds (s)

Converting to milliseconds: T = 0.00025 s * 1000 ms/s = 0.25 milliseconds (ms)

Converting to microseconds: T = 0.00025 s * 1000000 μs/s = 250 microseconds (μs)

The Productivity Index (PI) of the well is 2 psi/bbl per day. This indicates the efficiency of the well in delivering fluids from the reservoir to the wellbore.

The Productivity Index (PI) is a measure of the well's ability to deliver fluids from the reservoir to the wellbore. It is calculated by dividing the difference between the reservoir pressure and the flowing bottomhole pressure by the production rate. In this case, the reservoir pressure is given as 3,000 psi, and the flowing bottomhole pressure is measured at 2,990 psi. The production rate is 5 barrels per day.

For calculating the PI, use the formula:

PI = (Reservoir Pressure - Flowing Bottomhole Pressure) / Production Rate

Substituting the given values into the formula:

PI = (3,000 psi - 2,990 psi) / 5 bbls per day

Simplifying the equation:

PI = 10 psi / 5 bbls per day

PI = 2 psi/bbl per day

Therefore, the Productivity Index (PI) of the well is 2 psi/bbl per day. This indicates the efficiency of the well in delivering fluids from the reservoir to the wellbore.

Answer:

Explanation:

The create is moving at a constant velocity, so there is no acceleration and the crate is in equilibrium. This means the net force acting on the crate is 0. By Newton's second law, we have

n - w = 0

s - f = 0

where n denotes the magnitude of the normal force acting on the crate, w denotes its weight, s is the magnitude of the force applied by the person (s for sliding), and f is the magnitude of the kinetic friction force.

The friction force is proportional ot the normal force by a factor of µ, the coefficient of kinetic friction. So we have

n = w = (100 kg) (9.80 m/s²) = 980 N

s = f = µ n  →  325 N = µ (980 N)   →   µ = (325 N) / (980 N)

So the coeficient of kinetic friction is approximately µ ≈ 0.332.

velocity of drift. Axial drift velocity is another name for it. At the Fermi velocity, an electron will typically go through a conductor at random. This random motion will experience a minor net flow velocity in one direction as a result of an applied electric field.

Henry's Velocity can be calculated by dividing the distance he walked by the time it took him. The distance he walked is the difference between his initial position x=-12m and final position x=-47m, which is 35m (since -47m - (-12m) = -35m).

Answer:

The answer is B extrapolation

The process of predicting values that extend beyond the range of data points is called extrapolation, so option B is correct.

Extrapolation is a method of estimating a variable's value outside the original observation range using the relationship between the variable and another variable.

Extrapolation is comparable to interpolation in that it yields estimates between known observations, but extrapolation is more imprecise and more likely to yield meaningless findings. If identical approaches are assumed to be applicable, extrapolation may also refer to the extension of a method.

Creating a tangent line at the end of the known data and extending it past that point is known as linear extrapolation. Only when utilized to extend the graph of a roughly linear function or not too far beyond the existing data will linear extrapolation yield good results.

Therefore, the process of predicting values that extend beyond the range of data points is called extrapolation.
