Which planet moves the fastest and which planet moves slowest? a, b, c, d, e, or f. Explain

This question deals with the physics of resonance and sound. The possible frequency of the pano key is 258hz.

The beat of a frequency is the difference (an absolute value) in the frequencies produced by the two waves.

Beat per second equals |f1 - f2| Where

ft = Frequency of the Tunning fork and

fp= Frequency of the Piano Key

Hence

3 =  261 - fp

Solving for fp,

fp = 261-3

= 258hz

The frequency of the wave at the given period is 0.114 Hz. This frequency shows the number of revolution of the wave in a second.

The frequency of a wave is the number of revolutions of the wave per second.

Frequency of a wave is determined by taking the inverse of period of the wave.

The frequency of the wave at the given period is calculated as follows;

f = 1/T

Where;

f = 1/8.75

f = 0.114 Hz

Thus, the frequency of the wave at the given period is 0.114 Hz.

Answer:

seismic wave

Explanation:

Answer: 1.51 km

Explanation:

Coulomb's Law: The electrostatic force between two charge particles Q: and Q2 is directly proportional to product of magnitude of charges and inversely proportional to square of separation distance between them.

Or,   [tex]\vec{F}=k \frac{Q_{1} Q_{2}}{r^{2}}[/tex]

Where Q1 and Q2 are magnitude of two charges and r is distance between them:

Given:

Q1 = Charge near top of cloud = 48.8 C

Q2 = Charge near the bottom of cloud = -41.7 C

Force between charge at top and bottom of cloud (i.e. between Q: and Q2) (F) = 7.98 x 10^6N

k = 8.99 x 109Nm^2/C^2

So,

[tex]\begin{aligned}&7.98 \times 10^{6}=\left(8.99 \times 10^{9} \mathrm{Nm}^{2} / \mathrm{C}^{2}\right) \frac{48.8 \mathrm{C} \times 41.7 \mathrm{C}}{\mathrm{r}^{2}} \\&r=\sqrt{\frac{1.8294 \times 10^{13}}{7.98 \times 10^{6}}}=1.514 \times 10^{3} \mathrm{~m}=1.51 \mathrm{~km}\end{aligned}[/tex]

Therefore, the separation between the two charges (r) = 1.51 km

Daryl’s conclusion that the relationship between the frequency and the wavelength of sound waves in air is the result of causation is correct.

This is defined as the relationship between successive events when the first event brings about the other.

The expression for the block's centripetal acceleration is derived as ω²r or v²/r.

The centripetal acceleration of an object is the inward or radial acceleration of an object moving in a circular path.

The expression for the block's centripetal acceleration is derived as follows;

ω = dθ/dt

where;

ac = ω²r

where;

Also, ω = v/r

ac = (v/r)²r

The rate of climb of the aircraft in a steady climb making a 10 degree angle with the horizontal is : 17.36 knots

Given data

Airspeed = 100 knots

Angle with the horizontal ( ∅ ) = 10°

we will apply the formula below

Vy ( rate of climb ) = Airspeed * sin ∅

                              = 100 * sin ( 10 )

                              = 17.36 Knots

Answer:

Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.

Answer:

The intake of carbon dioxide (CO2) from the atmosphere causes ocean acidification, which is the continual decline in the pH value of the Earth's oceans. The burning of fossil fuels by humans is the primary cause of ocean acidification. The amount of carbon dioxide absorbed by the ocean grows in lockstep with the amount of carbon dioxide in the atmosphere. This causes a sequence of chemical reactions in the seawater, which has a negative impact on the, however, their rine life that lives beneath the surface. Carbonic acid is formed when carbon dioxide dissolves in seawater (H2CO3). The pH value of the ocean surface is estimated to have decreased from approximately 8.25 to 8.14 between 1751 and 1996, representing a nearly 30% increase in H+ ion concentration in the world's oceans (note that the pH scale is logarithmic, so a change of one pH unit equals a tenfold change in H+ ion concentration). The pH of the ocean in 2020 will be 8.1, according to the National Oceanic and Atmospheric Administration.

Explanation:

The medium for an ocean wave is the ocean water which involves movement on the water body.

This is defined as a substance or material that carries the wave. In the case of ocean waves, the medium is referred to the ocean water.

The medium is not transferred when a water wave moves on a lake as energy is transported but the water molecules aren't which is why lakes have water present in them.

One source error is deliberate deception and one of its solutions is having a lie scale inserted into the assessment.]

An error is a mistaken or erroneous action. In some contexts, an error is interchangeable with a mistake.

The discrepancy between the calculated value and the correct value is referred to as an "error" in statistics.

When a person is completely aware of what they are doing, they are engaging in deception. They are concealing the truth and making a deliberate decision to tell someone something that is false.

When describing a magic trick, such as a sleight of hand, the term deception can also be used.

When there are repetitive questions that ask the same questions over and over with different formats to check if the responses are constant over time, lie scales are utilized.

To calculate the energy in joules, simply enter the mass of ammunition (in grams) that you use, and the fps that you've read from your Chrono unit.

Since the magnetic flux through a coil of wire containing two loops changes at a constant rate from -58 wb to 38 wb in 0. 34 s, the emf induced in the coil is -5.65 V

The induced emf in the coil is given by ε = -NΔΦ/Δt where

Since ε = -NΔΦ/Δt

ε = -N(Φ₂ - Φ₁)/(t₂ - t₁)

Substituting the values of the variables into the equation, we have

ε = -N(Φ₂ - Φ₁)/(t₂ - t₁)

ε = -2(38 Wb - (-58 Wb))/(34 s - 0 s)

ε = -2(38 Wb + 58 Wb)/(34 s - 0 s)

ε = -2(96 Wb)/34 s

ε = -192 Wb/34 s

ε = -5.65 Wb/s

ε = -5.65 V

So, the emf induced in the coil is -5.65 V

The electrical action generated by a non-electrical source, measured in volts, is referred to as emf or electromotive force. Devices, such as batteries or generators, generate an emf by converting various sources of energy into electrical energy.

The emf induced in a coil is given by

[tex]\varepsilon = \dfrac{-N \times \triangle \phi}{ \triangle t}[/tex]

where

ΔΦ is the change in magnetic flux, Δt is the change in time, and N is the number of loops.

Given that the initial magnetic flux is -58 Wb while the final magnetic flux is 38 Wb. Also, the change in time is 0.34 seconds and the number of loops is 2. Therefore, the emf induced can be written as,

[tex]\varepsilon = \dfrac{-N \times \triangle \phi}{ \triangle t}[/tex]

[tex]\varepsilon = \dfrac{-(2) \times [38-(-58)]}{0.34}\\\\\varepsilon = -564.7\rm\ V[/tex]
