<span>Condensation is the change of
the substance from liquid to solid phase. Example of this is the formation of
ice. Vaporization is the change of substance from liquid to gas phase. Example of
this is the boiling of water. Deposition is the change of a substance from gas
to solid phase. Example of this is the formation of ice on a winter day. Sublimation
is the change of a substance from solid to gas phase. Example of this is dry
ice. The answer is letter C.</span>
part 1
mass = ρ x V
mass = 1739 kg/m³ x 3.8 km³ = 6608.2 kg
PE (potential energy)= mgh
PE = 6608.2 kg x 9.81 x 403
PE = 2.61 x 10⁷ J
part 2
megaton of TNT (Mt) =4.2 x 10¹⁵ J
convert PE to Mt:
2.61 x 10⁷ J : 4.2 x 10¹⁵ J = 6.21 x 10⁻⁹ Mt
It’s c.) I think so at least
Answer:
56km
Explanation:
168 ÷ 240 = 0.7
0.7 × 80 = 56km
240 is the amount of minutes in 4 hours.
We divided 168 by 240 to get the distance covered in 1 minute. Afterwards, we needed 80 minutes so we multiplied the answer by 80.
