Answer:

6000 K

Explanation:

The Sun's surface temperature is about 6000 K. It was estimated by obtaining its spectrum. The peak wavelength obtained from the spectrum indicates the surface temperature. The Wein's Displacement Law states that the surface temperature is inversely proportional to the wavelength.

T_{sun}=6000 K

What is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit
Tresset [83]

The highest frequency sound to which the machine can be adjusted is :

  • 4179.33 Hz

<u>Given data :</u>

Pressure = 10 Pa

Speed of sound = 344 m/s

Displacement altitude = 10⁻⁶ m

<h3>Determine the highest frequency sound ( f ) </h3>

applying the formula below

Pmax = B(\frac{2\pi f}{v}) A --- ( 1 )

Therefore :

f = ( Pmax * V ) / 2\pi \beta A

 = ( 10 * 344 ) / 2\pi * 1.31 * 10⁵ * 10⁻⁶

 = 4179.33 Hz

Hence we can conclude that The highest frequency sound to which the machine can be adjusted is : 4179.33 Hz .

<u><em>Attached below is the missing part of the question </em></u>

<em>A loud factory machine produces sound having a displacement amplitude in air of 1.00 μm, but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 Pa. Under the conditions of this factory, the bulk modulus of air is 1.31×105 Pa. The speed of sound in air is 344 m/s. What is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit?</em>

A marble dropped in still water will create circular ripples or waves. the radius of each circular wave will increase 4 centimet
Gnom [1K]

The circumference of the circle after t seconds = 25.12 t

Given data,

The radius of each circular wave will increase by four centimeters per second (cm/s)

In 1 second of circular wave radius = 4cm

In 1*t second of circular wave radius = 4t cm

 

As a result, the radius of the circular wave after t seconds is 4t cm.

We already know that the circumference of a circle is given by = 2πr, where r is the circle's radius.

As a result, the radius of a circular wave after t seconds is = 2π * radius of a circular wave after t seconds = 2π * 4t

                                                    = 8πt

( Taking π = 3.14 )

As a result, the circumference of the circle after t seconds = 8πt

                                                                                                     = 3.14t

                                                                                                   = 25.12t

How many times bigger is the radius of a helium atom then the radius of an alpha particle
kiruha [24]

The radius of a helium atom 4.8 times bigger  then the radius of an alpha particle.

<h3>What is alpha particle?</h3>

The structure of alpha particles, also known as alpha rays and alpha radiation, is similar to that of the helium-4 nucleus and has been made up of two protons as well as two neutrons bonded together.

<h3>What is helium?</h3>

For welding metals like aluminum, helium was utilized as an inert gas environment. It is also employed in rocket propulsion.

The radius of a helium atom 4.8 times bigger  then the radius of an alpha particle. More precisely than it's ever been, the diameter of the helium atom's nucleus, the alpha particle, had also been measured. Outcomes just point to a size of 1.6782 femtometers, 4.8 times more accurate than earlier readings.

To know more about helium  and alpha particle.
