Number of barrels are 3.0. Each barrel contains 42 gallons of oil. Thus, total volume of oil will be 42×3=126 gallons.
Converting gallons into m^{3}
1 gallon=0.00378 m^{3}
Thus, 126 gallons=0.4769 m^{3}
Thickness of oil film is 2.5\times 10^{2} nm, converting it into meters as follows:
1 nm=10^{-9} m
Thus,
2.5\times 10^{2} nm=1.5\times 10^{-7}m
Now, volume V of oil is related to area A and thickness T as follows:
V=A×T
rearranging,
A=\frac{V}{T}=\frac{0.4769 m^{3}}{2\times 10^{-7}m}=2.38\times 10^{6}m^{2}
Thus, square meters of oil will be 2.38\times 10^{6}m^{2}
I think that the answer is B that the sun (DOES NOT) support the processes of plate tectonics
That depends on how 'x' is related to 'y' and 'z' ... like the angles between all of them, and whether they're all on the same planet. A drawing would sure help.
Answer and Explanation: <u>Centripetal</u> <u>Acceleration</u> is the change in velocity caused by a circular motion. It is calculated as:
v is linear speed
r is radius of the curve the object in traveling along
For its first lap:
After a while:
Comparing accelerations:
<u>With linear speed </u><u>4 times faster</u><u>, centripetal acceleration is </u><u>16 times greater.</u>
