The correct answer is a, lunar eclipse
Answer:
This question is incomplete
Explanation:
The question is incomplete. However, to determine the time (in seconds) it took a worker to hit the ground from an elevated point. The speed the worker was coming with to the ground and the distance between the elevated point and the ground will have to be considered. Thus the formula to be used here will be
Speed (in meter per second) = distance (in meters) ÷ time (in seconds)
time (in seconds) = distance (in meters) ÷ speed (in meter per seconds)
P=4800kgm/s
As
p=mΔv
where p is momentum, m is mass and v is velocity
Given values is
m =1200kg
Δv= 17m/s-13m/s=4m/s
Now
p=mΔv
p=(1200kg)*(4m/s)
p=4800kgm/s
Answer:
There is no exception to this. all planets have some eccentricity. it is physically impossible to have an orbit without any eccentricity. However, venus's orbit has the lowest (0.007) eccentricity (closest to circular) so that could be your answer.
Mercury's orbit's eccentricity 0.2
Venus's orbit's eccentricity 0.007 (this is the lowest so it may be your answer)
Earth's orbit's eccentricity 0.0167
Mars's orbit's eccentricity 0.0934
Jupiter's orbit's eccentricity 0.0489
Saturn's orbit's eccentricity 0.0565
Neptune's orbit's eccentricity 0.009
Uranus's (yur,in,iss) orbit's eccentricity 0.0457
Pluto's (not really a planet) orbit's eccentricity 0.2444 (very high)
hope it helped.
