By considering the conservation of energy, the speed V of the spacecraft when it eventually crash into the earth and  its distance from the center of the earth is r are 11172.6 m/s and 3294.6 m/s respectively.

Given that, r is at infinity when a spacecraft has run out of fuel and its kinetic energy is zero. if only the gravitational force of the earth were to act on the spacecraft would eventually crash into the earth.

Where

Mass of the earth  [tex]m_{e}[/tex] = 5.97 × [tex]10^{24}[/tex] kg

Radius of the earth [tex]R_{e}[/tex] = 6.38 × [tex]10^{6}[/tex] m

G = 6.67 x [tex]10^{-11}[/tex]N[tex]m^{2}kg^{-2}[/tex]

a.)  Since the spacecraft is primarily moving through the near vacuum of space, the speed V of the spacecraft when it eventually crash into the earth can be calculated by considering the conservation of energy.

The total initial energy  =  total final energy.

[tex]E_{i} = E_{f}[/tex]

[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]

where [tex]K.E_{i}[/tex] = 0

-G[tex]m_{e}[/tex]m/(r + [tex]R_{e}[/tex]) = 1/2m[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex]m)/[tex]R_{e}[/tex]

mass of the spacecraft will cancel out

G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]

G[tex]m_{e}[/tex]/(r + [tex]R_{e}[/tex]) = 0 since r is at infinity.

0 =  1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/[tex]R_{e}[/tex]

Substitute all the parameters into the equation above.

0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/6.38 x [tex]10^{6}[/tex]

0.5[tex]V^{2}[/tex] = 62,413,636.36

[tex]V^{2}[/tex] =  62,413,636.36 / 0.5

[tex]V^{2}[/tex] = 124,827,272.7

V = [tex]\sqrt{124,827,272.7}[/tex]

V = 11172.6 m/s

b.) Given that the distance from the earth r = x([tex]R_{e}[/tex])

That is,

r = 11.5 x 6.38 x [tex]10^{6}[/tex]

r = 73,370,000 m

To find the spacecraft's speed when its distance from the center of the earth is r, we will use the same formula. That is,

[tex]K.E_{i}[/tex] + [tex]U_{i}[/tex] = [tex]K.E_{f}[/tex] + [tex]U_{f}[/tex]

0 =  1/2[tex]V^{2}[/tex] + ( -G[tex]m_{e}[/tex])/r

Substitute all the parameters into the formula

0 = 0.5[tex]V^{2}[/tex] + ( -6.67 x [tex]10^{-11}[/tex] x 5.97 x [tex]10^{24}[/tex] )/ 73,370,000

0.5[tex]V^{2}[/tex] = 5427272.727

[tex]V^{2}[/tex] = 10854545.45

V = [tex]\sqrt{10854545.45}[/tex]

V = 3294.6 m/s

Therefore, the speed V of the spacecraft when it eventually crash into the earth and  its distance from the center of the earth is r are 11172.6 m/s and

3294.6 m/s respectively.

Answer: option b it produces a contradictory urge to stop reading and to continue

Explanation:

Hope this helps

The correct response is - Option B results in a conflicting impulse to quit reading and to continue, which is the B answer.

In classical mechanics, the integral of both a force, F, over the time period over which it acts, t, is referred to as the "impulse." Impulse is a vector quantity since force is one as well. When an item receives an impulse, its linear momentum likewise changes in the opposite direction in an analogous vector.

The impulse function is a very brief pulse that can theoretically never end that is used to assess system dynamics. An impulse function in the real world is a pulse that is substantially shorter than the system's temporal response.

In physics, the term "impulse" is used to characterize or measure the impact of force operating gradually to alter an object's motion. The letter J stands for it, and is typically expressed in Newton-seconds

A recursive sequence is a sequence in which terms are defined using one or more previous terms which are given. If you know the nth term of an arithmetic sequence and you know the common difference , d , you can find the (n+1)th term using the recursive formula an+1=an+d .

Applying the inscribed angle theorem, the measure of ∠H is: C. 75°

Recall:

Since arc GH is congruent to arc FG, therefore:

m∠F = m∠H

Thus:

m∠H = 1/2(180 - m∠G)

m∠H = 1/2(180 - 30)

m∠H = 1/2(150)

m∠H = 75°

Therefore, applying the inscribed angle theorem, the measure of ∠H is: C. 75°

An arithmetic sequence is known to be a type of sequence that progresses through addition while a geometric sequence is one that progresses upward by multiplication.

Two new cells are formed at the end of the process of division of the cytoplasm (cytokinesis) or division of the cell nucleus (mitosis).

At the end of mitosis, the cell has two identical nuclei located at opposite cell ends, immediately the cytokinesis process is triggered, that is, the separation of both daughter cells.

Therefore, we can conclude that the reorganization between the generated daughter nuclei produces a fractionation of the cytoplasm and definitively separates the new cells.
