Answer: 3.751*10^18kg
Step-by-step explanation:
δ =619.09−0.000097p....equa1 where p (the distance from the center of the earth) is measured in meters and δ is measured in kilograms per cubic meter.
Calculating the density of air at 5km above earth surface
P = 5000m + 6370000m = 6.375*10^6m
δ = 619.09 -(.000097* 6.375*10^6)
δ = 0.715kg/m^3 = density
Since Mass = density*volume...equ2
To calculate volume of air around the spherical earth at height 5km
V = (4/3 pai R^3) - (4/3pai r^3) ...equation 3 where R =6.375*10^6m, r = 6.37*10^6
Substituting R and r in equation 2 to solve for volume of air
V = 1.085*10^21 - 1.08*10^21
V = 5.25*10^18m^3
Substituting δ and V into equation 2 to solve for mass of air
M = 0.715 * (5.25*10^18)
M = 3.751*10^18kg
Answer:
60%
Step-by-step explanation:
The 2100 people surveyed said they would buy it again, meaning they were satisfied. A total of 3500 people were surveyed.
So 2100 / 3500 = 60%
please give thanks :)
Answer:
1.75
Step-by-step explanation:
Just divide 14 by 8 and you get your answer !!!!
I think is B but idk how to do this but I could try
Answer:
16 pounds
Step-by-step explanation:
Total cereal she ate = 256 ounces
How many pounds she ate = ?
Given that (16 ounces = 1 pound)
Therefore, we have to divide the total ounces by 16 to calculate the cereal she ate in pounds = 256/16 = 16 pounds
