I agree on that. it's not like there is completely no force of gravity acting on them (I mean if they're still around the earth) , it's that it's so little that they can't even notice it. they'll float around and they seems like they have no weight. this is called weightlessness.

Express the answer in scientific notation. What is the pressure, in N/m2, at a depth of 50 km in the continental crust?

julia-pushkina [17]

Answer:

1.422 $\times 10^9$ N/m²

Explanation:

pressure (P) = ρ g h

where ρ= density of continental crust

g= acceleration due to gravity

h is the depth given

density of continental crust is equal to 2.9 g/cm³

= $\frac{2.9\times 10^{-3}}{10^{-6} } =2.9\times 10^3 kg/m^3$

g=9.81 m/s²

height = 50,000 m

now,

pressure (P) = ρ g h

pressure (P) = $2.9\times 10^3\times 9.81\times 50000$

=1.422 $\times 10^9$ N/m²
