Answer:
D = 0.2374 m
Explanation:
let D be the diameter of the image of mars, f be the focal length of the telescope mirror and β be the spatial resolution.
β = 6794×10^3/(5.58×10^7) = 0.1217562724
then:
The diameter of the telescope mirror is given by:
D = f×β
= (1.95)×(0.1217562724)
= 0.2374 m
Therefore, the diameter of the image of mars is 0.2374 m.
Are we talking about extinct?
I think it could be possible. However, the creature may not last long. Creatures from the distant past died off for a reason, they couldn't survive. So, with the sudden change in environment, they won't last long, especially if they didn't last in the past.

Answer:
69.74 N
Explanation:
We are given that
Weight of sled=49 N
Coefficient of kinetic friction
Weight of person=585 N
Total weight==mg=49+585=634 N
We know that
Force needed to pull the sled across the snow at constant speed,F=Kinetic friction
Where N= Normal=mg
Hence, the force is needed to pull the sled across the snow at constant speed=69.74 N
