Speed = distance ÷ time
Change 20 minutes to seconds...
20 × 60 = 120 seconds, because seconds (s) is the SI unit for time.
speed = 1000m/120s
= 8.33 m/s
The answer is Uranus. Its farthest distance from the Sun (aphelion) as point of reference is approximately 3 billion kilometers. Whereas Earth's distance from the Sun is about 150 million kilometers. Dividing Earth's distance to sun with the Uranus' distance to the Sun will give us the quotient of 20. Hence, Uranus is the planet that is 20 times farther from the Sun than the Earth is.
Characteristics help us to classify seeds because different plants have different features.
<h3>How are characteristics used to identify and classify plants?</h3>
The divisions classify plants that are based on whether they reproduce by spores or seeds. Spore-bearing plants include ferns, club mosses, and horsetail while on the other hand, Seed-bearing plants are divided into gymnosperms and angiosperms. Different plants have different characteristics and features so on the basis of these characteristics we can easily classify seeds whether they belong from angiosperm and gymnosperm.
So we can conclude that characteristics help us to classify seeds because different plants have different features.

Explanation:
(a) Impulse is force times time.
J = FΔt
J = (350 N) (0.12 s)
J = 42 Ns
(b) Change in momentum is equal to impulse.
J = Δp
Δp = 42 Ns
