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
The most common liquid on planet earth is water
Answer:
Explanation:
(a)
Since the earth is assumed to be a sphere.
Volume of atmosphere = volume of (earth +atm osphere) — volume of earth
Hence the volume of atmosphere is
(b)
Write the ideal gas equation as foll ows:

Hence the required molecules is 
(c)
Write the ideal gas equation as follows:
Hence the required molecules in Caesar breath is
(d)
Volume fraction in Caesar last breath is as follows:
(e)
Since the volume capacity of the human body is 500 mL.

Hi! The answer is C
As west is defined as negative, the trucks velocity is positive, since its travelling east. But its speed (absolute value of velocity) is decreasing, that means that the acceleration is negative.
