Answer:
The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
39929.4542466 m
Explanation:
Total mass of the asteroids

= Mass of Earth = 
The ratio is

The mass of the asteroids is 0.000334896182184 times the mass of the Earth.
Volume is given by

The diameter is 39929.4542466 m
Answer:
I think it might be A
Explanation:
the reason I think this answer is because the intensity is 50%.
Answer:29.4m/s
Explanation: Vf=Vi +at= 0 initial velocity +(9.8)(3)= 29.4 m/s
Answer:
Flow rate 2.34 m3/s
Diameter 0.754 m
Explanation:
Assuming steady flow, the volume flow rate along the pipe will always be constant, and equals to the product of flow speed and cross-section area.
The area at the well head is

So the volume flow rate along the pipe is

We can use the similar logic to find the cross-section area at the refinery

The radius of the pipe at the refinery is:



So the diameter is twice the radius = 0.38*2 = 0.754m
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that orbital velocity at certain height from the surface of Earth is given as

here we know that



now we have


Part b)
When a loose rivet is moving in same orbit but at 90 degree with the previous orbit path then in that case the relative speed of the rivet with respect to the satellite is given as
