Answer:
4.6s
Explanation:
v=u+at
0=22.5+(-9.8)t
-22.5=-9.8t
t=-22.5/-9.8
t=2.295 s
The total time will double
2.295×2=4.59s
=4.6s
Answer:
80.386 degrees
Explanation:
We use the cosine equation here (which is the adjacent side of the unknown angle divided by the hypotenuse
The adjacent side = 699ft
The hypotenuse = 1034ft
using cos∅ = Adjacent/hypotenuse
where ∅ is the unknown angle
cos ∅ = 699/1034 = 0.167
∅ = arccos 0.167 = 80.368°
As easy as one can imagine
<span>A tidally locked body in synchronous rotation (the moon) takes just as long to rotate around its own axis as it </span>does<span> to revolve around its partner (the earth). In other words, the moon spins on its axis at the same rate it orbits the earth.</span>
That's a pretty good intuitive definition of a <em>theory </em>.
The answer is most likely the letter B
