Most vibrating things have several resonant frequencies, and musical instruments often vibrate at harmonics of the fundamental frequency. An integer (whole number) multiple of the fundamental frequency is defined as a harmonic.

In a Piano the relation between harmonic and resonance frequency is n_{1} : n_{2} : n_{3} = 1:2:3.

"It is wave having frequency which is multiple integral of the fundamental frequency. The fundamental frequency is called first Harmonic. If a body starts vibration under impact of external vibrational force , is called Resonance. Since a Piano can produce all type of frequencies due to resonance therefore it produces melodious sound. Hence relation between harmonic and resonance frequency is n_{1} : n_{2} : n_{3}= 1:2:3."

The change of state that is shown here is from solid to liquid. The correct option is D.

A state of matter is one of the various forms that matter can take in physics. In everyday life, four states of matter are visible: solid, liquid, gas, and plasma.

In most environments, matter can exist in three distinct physical states: solid, liquid, and gas. In extreme environments, other states such as plasma, Bose-Einstein condensate, and neutron stars may exist.

Here in the given image, ice which is a solid is getting transformed into water i.e., liquid, so it can be considered that the phase is transforming from solid to liquid.

Answer:

The time taken for the charge to pass through the cross-section of the wire is 6.0s.

Given the data in the question;

Current; [tex]I = 5.0A[/tex]

Charge; [tex]Q = 30C[/tex]

Time; [tex]t = \ ?[/tex]

Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.

If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;

[tex]I = \frac{Q}{t}[/tex]

Where Q is the charge and t is time elapsed.

We substitute our given values into the expression above to determine the time it took the charge to pass through this wire.

[tex]I = \frac{Q}{t}\\ \\5.0A = \frac{30C}{t} \\\\t = \frac{30C}{5.0A} \\\\t = 6.0s[/tex]

Therefore, the time taken for the charge to pass through the cross-section of the wire is 6.0s.

Answer:

open

Explanation:

in open system mechanical energy is lost to its surroundings

The electron energy does not depend on the focusing cylinder voltage because the magnetic field runs perpendicular to the electron's direction of movement.

A magnetic field is produced by moving negatively electric charges (electrons) which generate magnetic forces that are observable.

The negative electrons that orbit around atoms in a molecule generate small magnetic fields around such atoms.

According to Fleming's left-hand rule, the direction of a magnetic force acting on a current is perpendicular to the direction of the electric current and magnetic field.

Because it exerts a force that's also parallel to the horizontal fields instead of in opposition to it, the final electron energy is unchanged by the focusing cylinder voltage.

An electron's energy is on the same scale (in the same range) as that of light. The lines in an element's spectrum represent changes in the energy of electrons within the element's atoms. Scientists have reached numerous conclusions regarding the behavior of electrons in atoms by studying these spectra.

Negative electrons orbiting around atoms in a molecule produce modest magnetic fields surrounding them.

The vector of a magnetic force that acts on a current is opposite to the axis of the electric current and magnetic fields, as per Fleming's left-hand rule.

Answer:

Explanation:

You need to consider the index of refraction.

index of refraction of air: 1.00

index of refraction of water: 1.33

Index of refraction of steel: 2.75681

If the sound wave passed from air into water, it passes from a lower index to a higher index of refraction.

As the wave travels into the more dense medium (higher n), it slows down. Therefore from air to water (lower to higher) it slows down, and from water to steel (n of steel is higher that n of water) therefore it slows down even more.

Since the kinetic energy is equal to the potential energy then the speed of the object is √2gh.

Average acceleration is the change in velocity with time.
Acceleration takes place when velocity changes with time. Velocity being a vector quantity may change in magnitude or direction any of the change results to acceleration

The pace at which a body's velocity varies is represented by average acceleration, which is a vector quantity.

The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.

The formula for acceleration is;

[tex]\rm a = \frac{v-u}{t}[/tex]

u is the initial speed

v is the final speed

The acceleration of the runner in the given time is 2.06m/s².

Given the data in the question;

Since the runner begins from rest,

Acceleration of the runner; [tex]a = \ ?[/tex]

Velocity is the speed at which an object moves in a particular direction.

Acceleration is simply the rate of change of the velocity of a particle or object with respect to time. Now, we can see the relationship from the First Equation of Motion

[tex]v = u + at[/tex]

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

To determine the acceleration of the runner, we substitute our given values into the equation above.

[tex]v = u + at\\\\13.4m/s = 0 + (a * 6.5s)\\\\13.4m/s = a * 6.5s\\\\a = \frac{13.4m/s}{6.5s}\\ \\a = 2.06m/s^2[/tex]

Hi there!

Recall the equation for the magnetic field of a wire (assuming infinite):

[tex]B = \frac{\mu _0 i_{encl}}{2\pi r}[/tex]

B = Magnetic field (T)
μ₀ = Permeability of Free Space (Tm/A)

i = enclosed current (A)
r = distance from wire (m)

From the equation, we can see that there is a DIRECT relationship between the current and the magnetic field.

Therefore, if the current is increased by a factor of 3, the FIELD will also be increased by a factor of three.
