The slowest animal ever discovered was a crab found in the Red Sea. It traveled with an average speed of 5.70km/yr. how long wou

Answer:
Time taken by the crab, t = 17.54 years.
Explanation:
It is given that,
Speed of a crab, v = 5.70 km/yr
Distance travelled by the crab, d = 100 km
We need to find the time taken by the crab to cover this much distance. Time taken is given by :
t = 17.54 years
So, the time taken by the crab is 17.54 years. Hence, this is the required solution.

<h2>Answer:

The velocity of a satellite describing a circular orbit is <u>constant</u> and defined by the following expression:
(1)
Where:
is the gravity constant
the mass of the massive body around which the satellite is orbiting
the radius of the orbit (measured from the center of the planet to the satellite).
Note this orbital speed, as well as orbital period, does not depend on the mass of the satellite. I<u>t depends on the mass of the massive body.</u>
In addition, this orbital speed is constant because at all times <u>both the kinetic energy and the potential remain constant</u> in a circular (closed) orbit.
I think you can just sub the values in? unless the qn is asking for smth else?
