They are both the waste of the sea and land
Henry's law states that:
P1/C1 = P2/C2
Where P = Pressure, and C = Solubility
In this case, P1 = 8.0 atm, C1 = 0.55 g/l, P2 = 5.0 atm, C2 =??
Therefore,
C2 = (P2*C1)/P1 = (5*0.55)/8 = 0.344 g/l
Answer:
Δ L = 2.57 x 10⁻⁵ m
Explanation:
given,
cross sectional area = 1.6 m²
Mass of column = 26600 Kg
Elastic modulus, E = 5 x 10¹⁰ N/m²
height = 7.9 m
Weight of the column = 26600 x 9.8
= 260680 N
we know,
Young's modulus=
stress =
=
= 162925
strain =
now,
Δ L = 2.57 x 10⁻⁵ m
The column is shortened by Δ L = 2.57 x 10⁻⁵ m
Explanation
El sodio tiene un número de masa de 23amu. Como el sodio tiene 11 protones, el número de neutrones debe ser 23-11 = 12 neutrones.
