Answer:
A) Earth and the other inner planets have higher average surface temperatures than the outer planets.
Explanation:
the earth and the other inner planets have higher average surface temperatures than the outer planets.
The reason for this response is due to the distance between the sun and the respective planet, the source of energy generation is the sun and the only way in which the temperature increase of each planet is guaranteed is by radiation, the further away a planet is from its star, its temperature will decrease. Although it is also important to highlight the atmospheric composition of the planet if this planet in its stratosphere has high density clouds that do not allow the entry of solar radiation, the temperature of the planet's surface will not increase, independent of the distance from the sun, but these are more complex cases where specialists in that area enter to perform a study in detail.
Missing question: "What is the spring's constant?"
Solution:
The object of mass m=6.89 kg exerts a force on the spring equal to its weight:
![F=mg=(6.89 kg)(9.81 m/s^2)=67.6 N](https://tex.z-dn.net/?f=F%3Dmg%3D%286.89%20kg%29%289.81%20m%2Fs%5E2%29%3D67.6%20N)
When the object is attached to the spring, the displacement of the spring with respect to its equilibrium position is
![\Delta x=43.2 cm-33.6 cm=9.6 cm=0.096 m](https://tex.z-dn.net/?f=%5CDelta%20x%3D43.2%20cm-33.6%20cm%3D9.6%20cm%3D0.096%20m)
And by using Hook's law, we can find the constant of the spring:
<span><span>Velocity is a vector, and the initial and final ones are in opposite directions.
There must have been acceleration in order to change the direction of motion.</span>
A) No. The initial and final velocities are the same.
This is all wrong, and not the correct choice.
It's "Yes", and the initial and final velocities are NOT the same.
B) Yes. The ball had to slow down in order to change direction.
This is poor, and not the correct choice.
The "Yes" is correct, but the explanation is bad.
Acceleration does NOT require any change in speed.
C) No. Acceleration is the change in velocity. The ball's velocity is constant.
This is all wrong, and not the correct choice.
It's "Yes", there IS acceleration, and the ball's velocity is NOT constant.
D) Yes. Even though the initial and final velocities are the same, there is a change in direction for the ball.
This choice is misleading too.
The "Yes" is correct ... there IS acceleration.
The change in direction is the reason.
The initial and final velocities are NOT the same. Only the speeds are.

Θ
Θ
Θ = ![tan^{-1}(\frac{v^{"} _{1} }{v_{1} } )](https://tex.z-dn.net/?f=tan%5E%7B-1%7D%28%5Cfrac%7Bv%5E%7B%22%7D%20_%7B1%7D%20%7D%7Bv_%7B1%7D%20%7D%20%29)
Explanation:
Applying the law of conservation of momentum, we have:
Δ![p_{x = 0}](https://tex.z-dn.net/?f=p_%7Bx%20%3D%200%7D)
![p_{x} = p"_{x}](https://tex.z-dn.net/?f=p_%7Bx%7D%20%3D%20p%22_%7Bx%7D)
Θ (Equation 1)
Δ![p_{y} = 0](https://tex.z-dn.net/?f=p_%7By%7D%20%3D%200)
![p_{y} = p"_{y}](https://tex.z-dn.net/?f=p_%7By%7D%20%3D%20p%22_%7By%7D)
Θ (Equation 2)
From Equation 1:
Θ
From Equation 2:
sinΘ = ![m_{1} v_{1}](https://tex.z-dn.net/?f=m_%7B1%7D%20v_%7B1%7D)
![v"_{1} = \frac{m_{2} v"_{2}sinΘ}{m_{1} }](https://tex.z-dn.net/?f=v%22_%7B1%7D%20%3D%20%5Cfrac%7Bm_%7B2%7D%20v%22_%7B2%7Dsin%CE%98%7D%7Bm_%7B1%7D%20%7D)
Replacing Equation 3 in Equation 4:
![v"_{1}=\frac{m_{2}\frac{m_{1}v_{1}}{m_{2}cosΘ}sinΘ}{m_{1}}](https://tex.z-dn.net/?f=v%22_%7B1%7D%3D%5Cfrac%7Bm_%7B2%7D%5Cfrac%7Bm_%7B1%7Dv_%7B1%7D%7D%7Bm_%7B2%7Dcos%CE%98%7Dsin%CE%98%7D%7Bm_%7B1%7D%7D)
![v"_{1}=v_{1}\frac{sinΘ}{cosΘ}](https://tex.z-dn.net/?f=v%22_%7B1%7D%3Dv_%7B1%7D%5Cfrac%7Bsin%CE%98%7D%7Bcos%CE%98%7D)
Θ (Equation 5)
And we found Θ from the Equation 5:
tanΘ=![\frac{v"_{1}}{v_{1}}](https://tex.z-dn.net/?f=%5Cfrac%7Bv%22_%7B1%7D%7D%7Bv_%7B1%7D%7D)
Θ=![tan^{-1}(\frac{v"_{1}}{v_{1}})](https://tex.z-dn.net/?f=tan%5E%7B-1%7D%28%5Cfrac%7Bv%22_%7B1%7D%7D%7Bv_%7B1%7D%7D%29)
