A meteor moving 468 km per minute traveling in a south-to-north direction passed near Earth in 2013. Because the meteor was only 45 m wide and was 27,700 km above Earth's surface, it was not visible without the aid of a telescope. Which statement describes the meteor's motion?

A. Its velocity was 468 km/min northward

B. Its acceleration was 468 km/min2.

C. Its speed was 468 km/min northward.

D. Its velocity was 468 km/min2

answer; /// i believe the correct answer is (thrombocytopenia); (a)

a chair, a bed, and a toothbrush

explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
