4.6 billion years ago - most likely hydrogen (H2) and helium (He)
probably rich in hydrogen compounds like methane (CH4), ammonia (NH3), hydrogen cyanide (HCN), water (H2O), and formaldehyde (HCHO). Also some N2, CO2 but LITTLE or NO free oxygen.
Molecules of H2 and He move really fast, especially when warm, that they eventually all escaped Earth's gravity and drifted off into space.
Answer:
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earth's surface, which forces scale to vary across a map. Because of this variation, the concept of scale becomes meaningful in two distinct ways.
Explanation:
Answer:
Rect. Prism SA= 251. 75ft²
Cube SA= 8664in²
Cube SA= 6a²
Explanation:
SA= 2(lh+wh+lw)
Cube SA= 6a²
Rect. Prism SA
Assuming length(l)=11.5, width(w)=3.25 and height(h)=6
SA=2(lh+wh+lw)
=2(11.5×6+3.25×6+11.5×3.25)
=2(69+19.5+37.325)
=2×125.875
=251.75ft² (rounding is optional if you like)
Cube SA
SA=6a² (<em>a</em><em> </em><em>referring</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>edges</em><em>/</em><em>sides</em><em>)</em><em> </em>
<em> </em><em> </em><em> </em><em> </em><em> </em>=6× 38²
=6×1444
=8664in²
Hope this helped.
