Information about the problem:

Using the formula of the sphere area we get:

a = 4 * π * r²

a = 4 * 3.1416 * (5.0 m)²

a = 314.16 m²

Applying the pressure formula we get:

P = F/a

P = 45 N/314.16 m²

P = 0.1432 Pa

They appear to recede from our viewpoint.

That is, their emitted spectra are shifted toward the red (red-shift).

The wave-lengths that are received on earth are somewhat longer because of the "Doppler" shift of the receding atoms.

The correct answer for  the ratio of the area under the catenary to its arc length is 12 : 1 .

y = 12cosh(x/12) Since the анс length from FGN) on the interval [c, d] is Arc length =

Let y' =f'(x)  prime  = derivative of 12cosh(x/12) for x = Sinh(x/12) .

. A(x)  length = ∫√1+ Sinh² (1/2). dx

= int c ^ d sqrt(cosh^2 (alpha/12)) * dx

= integrate  d from c to d cosh( x 12 )* dx

=[12. sinh(x/12) ] e ^ d

= 12[sinh(d/12) - sinh(c/12)]

and area under f(x) on the interval [c, d]

Area = ∫ f(x).dx from [c,d ]

= 144[sinh(d/12) - sinh(c/12)]

the area ratio of the area under the catenary to it's length is

= 144[sinh((d)/12) - sinh(c/12))/ 12[sinh( d/ 12 ) -sinh( c /12 )] .

Einstein was the first to postulate that light is made up of photons, which are essentially energy bundles.

A photon is a microscopic particle made up of electromagnetic radiation waves. Maxwell demonstrated that photons are merely electric fields moving through space. Photons move at the speed of light and have no charge or rest mass. Charged particles produce photons, though they can also be produced by other processes, such as radioactive decay.

It's common to refer to photons as energy packets. This analogy is excellent because a photon has uncondensable energy. An alternating electric field is how this energy is kept in reserve. The universe's size, which is the longest theoretical wavelength of light, and the Planck length, which some theories claim to be the smallest, have never been measured. These energy packets may travel great distances without losing energy or speed. In vacuum, photons move at the speed of light, which is 2.997 x 108 m/s.

Although the hydrogen bonds in water are much too weak to be compared to intra - molecular bonds like covalently or ionic bonds, they are nevertheless strong enough to require a lot of energy to break. Water boils at 100°C for this reason.

Copernicus measurements of the orbital radii of six of the planets were very accurate compared to our modern values.

This theory put the Sun in the centre of the cosmos, stationary, and had Earth and the other planets orbit it at uniform speeds in circular orbits modified by epicycles. The geocentric Ptolemaic paradigm, which put Earth at the centre of the cosmos for ages, was replaced by the Copernican model.

The velocity vector is v(t) = 6t i + 3t j + k, and the position vector is r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i.[/tex]

We have to integrate the specified acceleration vector to obtain the velocity vector of the particle before integrating the velocity vector to obtain the position vector of the particle.

So, the acceleration vector: a(t) = 6i + 3j

We will the find the velocity vector,

To find the velocity vector, we integrate the acceleration vector with respect to time 't':

∫a(t) dt = ∫(6i + 3j) dt

when we integrate with respect to time 't' that gives us:

v(t) = 6t i + 3t j + C

where 'C' is the constant of integration.

Using the initial velocity condition to find 'C':

Given initial velocity: v(0) = k

Substitute t = 0 into the velocity vector equation:

v(0) = 6(0) i + 3(0) j + C

k = C

So, C = k

We put the value of 'C' back into the velocity vector equation:

v(t) = 6t i + 3t j + k

Calculate the position vector r(t):

To find the position vector, we integrate the velocity vector with respect to time 't':

∫v(t) dt = ∫(6t i + 3t j + k) dt

Integrating with respect to time 't' gives us:

r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + D[/tex]

where 'D' is the constant of integration.

We use the initial position condition to find 'D':

Given initial position: r(0) = i

Substitute t = 0 into the position vector equation:

r(0) = [tex]\rm 3(0)^2 i + (3/2)(0)^2 j[/tex]+ k(0) + D

i = D

So, D = i

when we put the value of 'D' back into the position vector equation:

r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i[/tex]

Therefore, the velocity vector is v(t) = 6t i + 3t j + k, and the position vector is r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i.[/tex]

Answer:

A mature star is a star that has exhausted its supply of hydrogen

Explanation:

For the most part, a star is powered by nuclear fusion. The energy is first produced by the fusion of hydrogen atoms in the core of a main-sequence star. Later, when the helium predominates in the core, stars like the Sun begin to fuse hydrogen along a spherical shell around the core. This allows the star to steadily increase in size, passing through the subgiant stage and eventually reaching the red giant stage.

When they reach this stage, the hydrogen in them nearly completely depletes, and they get brighter and hotter, eventually becoming low-mass white dwarfs.

When a star's supply of hydrogen in its core runs out, leaving only helium, the outward force provided by fusion begins to diminish, and the star can no longer maintain equilibrium. When the force of gravity exceeds the force of internal pressure, the star begins to disintegrate. The outcome of this collapse is determined by the mass of the star.
