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:
17.5, or 35/2
Step-by-step explanation:
First of all, the formula for volume is V=lwh. Replace V with 1050, w with 16m, and h with 3.75, since these values are already given.
The equation should look like this:
1050 = l*16*3.75
By solving for l, you'll get 17.5, or 35/2
Answer:
Step-by-step explanation:
Given: Events A and B are such that and P(A∩B) = 17
To find:
Solution:
Probability refers to the chances of occurrence of any event.
An event is described as an outcome of a random experiment.
A random experiment is an experiment for which outcomes cannot be predicted.
P(A∩B) ÷ P(B) =
