The speed of the wave will be v= 448.07 m/s
What is speed of the wave?The speed of the wave is defined as the distance traveled by the wave with respect to the time.
The frequency is defined as the number of cycles per seconds it is calculated in hertz
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
Now frequency = 173 hertz
wavelength = 2.59 m
The velocity will be given by the formula:
[tex]v=\lambda\times f[/tex]
[tex]v=173\times 2.59=488.07 \ \frac{m}{s}[/tex]
Thus the speed of the wave will be v= 448.07 m/s

What does a 'dead' battery mean chemically? a) q > 1 b) q < 1 c) q = 1 d) q = k e) q/k = 0
Answer:
d) q=k
Explanation:
When a battery is "dead" it means that the chemical components are at equilibrium. When that occurs,
Δ
G
= 0, and Q = K.
A 'dead' battery mean chemically Q=1. At this position, the battery is at equilibrium condition, and considered as dead.
What is dead battery?Dead battery is the battery in which no flow of electron take place as there is no potential difference.
Chemically, the battery is considered as dead battery, when there is no chemical process happens in battery.
Q is a reaction quotient of Nernst Equation for a battery.At the equilibrium condition, the value of Q is to become equal to 1. At this condition, the battery is considered as dead.Thus, a 'dead' battery mean chemically Q=1. At this position, the battery is at equilibrium condition, and considered as dead.

Answer:
a because they are bigger and have more mass wich means that they will fall faster because there is more weight going downward...
Explanation:
Beluga
Answer:
Explanation:
It depends on whether this is a "trick" question.
The law of universal gravitation says that the attractive force between two objects depends directly on their masses and inversely to the square of distance in between them.
As the objects in A are bigger than B, they MAY have higher masses. So the force is larger in A.
But no information is given about object mass or density. The distance between objects in B is shorter. So if the objects in B have the same masses those in A, then the force is larger in B.
What is fission and how is it related to atomic energy
Answer:
Fission is the release of atomic energy related to the splitting of nuclei.
M = M1 + M2 + E where E = m c^2 energy from conversion of mass
if the daughter nuclei are less in total mass than the parent nucleus then the difference is released as atomic energy where E = m c^2 and m is the mass that has been lost in the conversion.

Sound waves cannot travel through empty space.
Sound waves can travel through liquids.
Light waves are not true waves.
Light waves need matter in order to travel.
Waves can only move matter up and down or from side to side.
Answer:
Sound waves cannot travel through empty space
sound can travel through liqui
Sound waves cannot travel through empty space but can travel through liquids. Waves make the particles of matter up and down but do not along with them. The light waves are not true mechanical waves. Therefore, options (A), (B), (C), and (E) are correct.
What are sound waves?Sound can transmit through liquids, gases, and plasma as longitudinal waves, also known as compression waves. It needs a medium to propagate so it can be propagated through solids as both longitudinal waves and transverse waves.
Longitudinal sound waves contain alternating pressure deviations causing compression and rarefaction, while transverse waves have waves of alternating shear stress perpendicular to the direction of propagation.
Waves can make matter move up and down or from side to side but do not carry along with them. Light waves are not considered true waves because they carry without the involvement of the motion of matter.

Why does the law of conversion of mass make sense?
Explanation:
If u mix 1g of salt with 100 ml of water, both dissolves but at the same time the mass of the solution increases.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction
Answer:
The law of conservation of mass was crucial to the progression of chemistry, as it helped scientists understand that substances did not disappear as result of a reaction as they may appear to do; rather, they transform into another substance of equal mass.

Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields.
What is electromagnetic waves?Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields. Electromagnetic waves/radiation possess the ability to travel through vacuum (i.e. they do not require a material medium for their propagation) while also carrying radiant energy.
Electromagnetic fields which are the sources of electromagnetic radiation, exist as a result of the combination and interaction of travelling electric and magnetic field forces.
Electromagnetic radiations consists of the following waves: radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays.
These waves have differing and unique properties such as wavelength, frequencies, ionizing properties, penetrating ability, sources as well as well as uses. However, they have a common property of velocity- they travel with the speed of light, 3.0 * 10⁸ m/s.
In addition to having the same velocity, all electromagnetic radiation exhibit interference and diffraction.

4A can be correct
The correct option is: 2A cm
What is simple harmonic motion?In a simple harmonic motion, the particle moves back and forth around a mean position. The distance covered by the particle in one time period depends on the amplitude of the oscillation.
The time period (T) of a simple harmonic motion can be expressed in terms of the frequency (f) as:
T = 1/f
The frequency (f) of a simple harmonic motion can be related to the angular frequency (ω) as:
ω = 2πf
Therefore, the time period (T) can also be expressed in terms of the angular frequency (ω) as:
T = 2π/ω
The displacement of the particle at any time (t) during the simple harmonic motion can be expressed as:
x = A cos(ωt)
where x is the displacement, A is the amplitude, and cos(ωt) is the cosine function.
The particle moves from its initial position to its maximum displacement (+A), then back to its initial position, and finally to its maximum displacement in the opposite direction (-A), before returning to its initial position again. Therefore, the distance covered by the particle in one time period is twice the amplitude (2A).
Therefore, the correct option is:
