The amplitude of a transverse wave on a string is 3.0 cm. The ratio of the maximum particle speed to the speed of the wave is 3.9. What is the wavelength (in cm) of the wave?

Answers

Answer 1

Answer:

Answer:

Therefore the wavelength of the particle is 4.83 m.

Explanation:

Transverse wave: A transverse wave is a moving wave whose direction of wave and oscillation are perpendicular to each other.

Amplitude:The amplitude of a wave is the maximum the distance from its rest position covered by a particle.

Here amplitude (A) = 3.0 cm

The ratio of maximum speed to the speed of the particle is 3.9

The maximum speed of the particle $C_(max)$ = A×ω

The speed of the particle C= f×λ

Then,

$(C_max)/(C) =(A* \omega)/(f* \lambda)$

$\Rightarrow (C_max)/(C) =(A* 2\pi * f)/(f* \lambda)$ [∵ω=2πf]

$\Rightarrow (C_max)/(C) =(A* 2\pi )/( \lambda)$

$\Rightarrow 3.9=(3* 2\pi )/( \lambda)$

$\Rightarrow \lambda=(3* 2\pi )/( 3.9)$

$\Rightarrow \lambda = 4.83$ m

Therefore the wavelength of the particle is 4.83 m

A material that can easily flow is called aa. fluid.
b. solid.
c. buoyant force.
d. hydraulic material.

Answers

Answer:

a. fluid

Explanation:

A fluid is any body that has the property to flow, and lacks rigidity and elasticity, and consequently yields immediately to any force tending to alter its shape and thus adopting the shape of its container. Fluids can be liquids or gases according to the different intensity of the cohesion forces existing between their molecules. In liquids, intermolecular forces allow particles to move freely, although they maintain latent bonds that cause substances in this state to have a constant or fixed volume. Gases, by contrast, consist of well-separated moving particles that collide with each other and try to disperse, such that the gases have no defined shape or volume.

As the speed of a fluid increases, ____.a. the pressure decreases
c. the force decreases
b. the pressure increases
d. the volume decreases

Answers

The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.

Answer:

a. the pressure decreases

Explanation:

If we assume here the flow of the fluid to be ideal flow such that there is no viscous loss in the fluid then in this case we can say that Bernoulli's theorem is valid here.

so here we can say

$P + \frac{1]{2}\rho v^2 = constant$

now here from above equation we can say that sum of pressure and kinetic energy of fluid will remain constant always

Now if speed of flow of the fluid is increased then to sum remain constant in ideal flow the pressure must have to decrease here.

so correct answer would be

a) the pressure decreases
