D = kinetic energy / net force (thrust minus gravity) when there's no drag. The E = formula is related to velocity and F = ma is related to acceleration. So in other words the rate of change of Force is proportion to the rate of change of acceleration multiplied by the scaler mass.
D) Troposphere.
Hope this is of help to you, and happy studying~!

Ag2Co3 ->2Ag(+) +CO3(2-)
Ksp=(Ag)^2 (Co3(2-)
Concentration of Ag=0.000253m
Concentration of CO3(2-)=0.000127m
Ksp=(0.000253)^2*0.000127
=8.12*e^-12
Answer:
Molarity = 0.72M
Molality = 0.85M
Explanation:
Molarity and molality are two measures of molar concentration, and they can be calculated as follows:
Molarity = number of moles/volume of solvent
Molality = number of moles/mass (kg) of solvent
Mole = mass/molar mass
Molar mass of stilbene (C14H12) = 12(14) + 1(12)
= 168 + 12
= 180g/mol
mole of stilbene = 13/180
mole = 0.072mol
Volume = 100mL = 0.1L
molarity = 0.072/0.1
Molarity = 0.72M
Molality = number of moles ÷ mass (kg) of solvent
To get mass of solvent, we use;
Density = mass/volume
Mass = density × volume
Mass = 0.85g/mL × 100mL
Mass = 85g
Mass in kg = 85/1000 = 0.085kg
Molality = 0.072/0.085
Molality = 0.847M
Molality = 0.85M
Answer:
The frozen part of the hydrosphere has its own name, the cryosphere. Water moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans.
