The last stage of a medium mass star is the white dwarf stage

White Dwarf Stage

  • This ring is called a planetary nebula. when the last of the helium atoms in the core are fused into carbon atoms, the medium size star begins to die. Gravity causes the last of the star's matter to collapse inward and compact. This is the white dwarf stage.

How much force is needed to accelerate a 9760 kg airplane at a rate of 4.6 m/s^2
seropon [69]
Assuming air resistance / friction is negligable:

force = mass × acceleration

f = m × a
f = 9760 × 4.6
f = 44896N

f= 45kN (2 sig fig)

the length of the eye and the curvature of the cornea determine the refractive error of an eye. hyperopia, or farsightedness, is
N76 [4]

True, the length of the eye and the curvature of the cornea determine the refractive error of an eye. Hyperopia, or farsightedness, is produced by a shorter-than-normal eye.

<h3>What is Hyperopia?</h3>

With farsightedness (hyperopia), a common visual issue, you may be able to see far objects clearly but have hazy vision of nearby items.

Your ability to focus is influenced by how farsighted you are. People with severe farsightedness might only be able to see objects that are far away clearly, whereas people with mild farsightedness might be able to see objects that are nearby clearly.

<h3>Symptoms</h3>

Being farsighted can mean:

Nearby objects might seem hazy

Squinting is required to see clearly.

You experience eye pain or discomfort around the eyes as well as eyestrain.

After performing close work, such as reading, writing, using a computer, or sketching, for a while, you have general eye discomfort or a headache.

<h3>A distortion of focus</h3>

Your cornea or lens must be uniformly and smoothly bent to allow light to pass.

You have a refractive error if your cornea or lens are not uniformly and smoothly curved, which causes improper light refraction.

When your cornea is overly flat or your eyeball is shorter than normal, you develop farsightedness. Nearsightedness has the opposite impact.

How do i solve A sound wave has a frequency of 658 Hz in air
kiruha [24]

Answer:

-47 °C

Explanation:

Speed of sound in air at sea level is:

v = 331 m/s + 0.6 m/s/°C T

where T is the temperature in Celsius.

The speed of sound is also the frequency times the wavelength:

v = fλ

Therefore:

fλ = 331 m/s + 0.6 m/s/°C T

(658 Hz) (0.46 m) = 331 m/s + 0.6 m/s/°C T

302.68 m/s = 331 m/s + 0.6 m/s/°C T

-28.32 m/s = 0.6 m/s/°C T

T = -47.2 °C

Rounding to two significant figures, the temperature is -47 °C.

A distant star gives off a visible range of light whose color depends on its temperature. Which model of light does this example
aleksklad [387]

The statement 'a distant star gives off a visible range of light whose color depends on its temperature' is supported by the wave model​.

<h3>What is wavelength?</h3>

The wavelength can be defined as the periodic distance of a given wave that repeats in a constant way.

The emissivity of particles is a function of both wavelength and temperature of a given material/object. Visible wavelengths range from 700 nm to 400 nm (violet color).

Star temperature largely determines its color, blue stars are warmer than yellow and red stars, and red stars are cooler than yellow stars.
