Which statement correctly compares the values in the statement?.
The statement that compares values are;
0.45 > 0.0045 -0.45 < 0.0045.What is a value?
value can be regarded as the representation of some entity, and this entity give room for manipulation by a program.
They compares values because we can see that 0.45 is larger than 0.0045 in 100 times. -0.45 is lesser than 0.0045
Therefore, 0.45 > 0.0045 and -0.45 < 0.0045 compares values.

very far from earth (at r=[infinity]), 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 it (i.e., neglect the forces from the sun and other solar system objects), the spacecraft would eventually crash into the earth. the mass of the earth is me and its radius is re. neglect air resistance throughout this problem, since the spacecraft is primarily moving through the near vacuum of space.
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.

After mitosis and cytokinesis are complete which of the following are true.
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.
In the entire process of cell division and cytokinesis, chromosomes condense, line up on the equatorial plate, and migrate toward the poles simultaneously.When migration ends, the barriers that separate the new nuclei and the new cells are formed.Therefore, we can conclude that the reorganization between the generated daughter nuclei produces a fractionation of the cytoplasm and definitively separates the new cells.

triangle FGH is inscribed in the circle above. If FG is congruent to GH and the measure of G is 30 what is the measure of H
Applying the inscribed angle theorem, the measure of ∠H is: C. 75°
Recall:
Based on the inscribed angles theorem, the measure of an inscribed angle = half of the measure of the intercepted arc.Since arc GH is congruent to arc FG, therefore:
m∠F = m∠H
Thus:
m∠H = 1/2(180 - m∠G)
Substitutem∠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°

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.
What is an Impulse?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
