Answer:
The angular velocity is 
Explanation:
From the question we are told that
The mass of each astronauts is 
The initial distance between the two astronauts 
Generally the radius is mathematically represented as 
The initial angular velocity is 
The distance between the two astronauts after the rope is pulled is 
Generally the radius is mathematically represented as 
Generally from the law of angular momentum conservation we have that
Here 
is the initial moment of inertia of the first astronauts which is equal to 
the initial moment of inertia of the second astronauts So
Also 
is the initial angular velocity of the first astronauts which is equal to 
the initial angular velocity of the second astronauts So
Here 
is the final moment of inertia of the first astronauts which is equal to 
the final moment of inertia of the second astronauts So
Also 
is the final angular velocity of the first astronauts which is equal to 
the final angular velocity of the second astronauts So
So

Answer:
it is because they can store and retrieve informatiion just like human beings
Answer;
-The rocks are the same age
Explanation;
Seafloor spreading is the process by which the seafloor moves apart at mid-ocean ridges. Divergent seafloor spreading occurs at this type of plate boundary.
Seafloor spreading and other tectonic activity processes are the result of mantle convection. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense.
Answer:
50m/s.
Explanation:
Let's take acceleration as A and speed as S:
A = 5m/s²
S = A × 10s = 5 × 10 = 50m/s
The answer is 50m/s.
