Lubov Fominskaja [6]2 years ago
4 0

Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "<u>115.87Hz</u>."

<h3>What is the frequency of a sound source?</h3>

The <u>frequency of a sound source</u> is the quantity of waves that move through a point per unit of time.

Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.

Therefore, in this case, we have

Velocity (v) of sound in air = 343 m/s

Wavelength (λ) = 2.96 m

Frequency (f) =?

f = v ÷ λ

f = 3.43m/s ÷ 2.96m

=> 115.87Hz

Hence, in this case, it is concluded that the correct answer is 115.87Hz.

A typical neutron star has a mass of about 1. 5msun and a radius of 10 kilometers
Triss [41]

How thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

<h3>Density of the Neutron star</h3>

Density

ρ = m / V

Where:

ρ= density

m = mass of the planet 5.98 10²⁴ km

V =volume of the spherical layer

Volume of a sphere

Volume = 4/3 π r³

Mass = 1.5 = 1.5 1,991 10³⁰

Mass= 2.99 10³⁰ kg

Density:

ρ = 2.99 10³⁰ / [4/3 π (10 10³)³]

ρ is = 7.13 10 17 kg / m³

V = 5.98 10²⁴ / 7.13 10¹⁷

V = 8,387 10⁶ m³

Thickness of the layer

V = 4π r² e

e = V / 4π r

e = 8,387 10⁶ / [4π (10 10³)²]

e = 6.67 10⁻³ m

Inconclusion how thick a layer would Earth form as it wraps around the neutron star’s surface is: 6.67 10⁻³ m.

Quizlet renal autoregulation consists of myogenic mechanism and tubuloglomerular feedback
weqwewe [10]

The two different systems which are responsible for renal autoregulation are:

  1. Myogenic mechanism
  2. Tubuloglomerular feedback mechanism.

<h3>What is renal autoregulation?</h3>

Renal autoregulation mechanism is a kind of myogenic autoregulation which maintains a constant renal blood flow at varying arterial pressure.

So therefore, The two different systems which are responsible for renal autoregulation are: Myogenic mechanism

and Tubuloglomerular feedback mechanism.
