Answer
What makes up a perfect planet? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon. Proportionate Ozone Layer and Light amount. According to the panspermia hypothesis, microscopic life—distributed by meteoroids, asteroids and other small Solar System bodies—may exist throughout the Universe. This is the perfect planet. In the end a perfect planet includes SUSTAINBLE DEVELOPEMNT IN EVERY ASPECT OF LIFE!
Explanation:
We have

The quantity is converted to the required units.
<u>Answer</u>
B•Horizontal=11.49 m/s
Vertical=9.64 m/s
Using the concept of a trigonometric ratios,
sin θ = y/hypotenuse
where y is the vertical component.
sin 40 = y/15
y = 15 × sin 40
= 9.64 m/s
vertical component = 9.64 m/s
cos θ = x/hypotenuse
where x is the horizontal component
cos 40 = x/15
x = 15 × cos 15
=11.49
Horizontal component = 11.49 m/s
Her total distance was 200 meters, since she ran 100 meters west and the same 100 meters back. This gives an average speed of 200 m / 40 s = 5 m/s.
However, her displacement was 0, since she ended at the same place she began, therefore, her average velocity is 0 / 40 s = 0.
Misleading or not answered correctly. Or, not diverse enough.
