Question
) 9) Suppose 1.0 cubic meter of oil is spilled into the ocean. Find the area of the resulting slick, assuming that it is one molecule thick, and that each molecule occupies a cube 0 .50 m on a side.10) New York is roughly 3000 miles from Seattle. When it is 10:00 A.M. in Seattle, it is 1:00 P.M. in New York. Using this information, estimate (a) the rotational speed of the surface of Earth, (b) the circumference of Earth, and (c) the radius of Earth. ) 9) Suppose 1.0 cubic meter of oil is spilled into the ocean.

10) New York is roughly 3000 miles from Seattle. When it is 10:00 A.M. in Seattle, it is 1:00 P.M. in New York. Using this information, estimate (a) the rotational speed of the surface of Earth, (b) the circumference of Earth, and (c) the radius of Earth.
Explanation / Answer
9 Ans: The volume of oil is V1=1 m33
After the oil is spilled the volume is V2= Area occupied ×height of the molecule
But here V1=V2, So, The area occupied is 1/(5E-6)= 2E6 m2 =200000 m2
10 Ans:
a)With respect to Sun reference frame :
The rotational speed of surface of earth is 3000 mi/ 3hrs =1000 mi/hr
b) We know for one rotation it takes 24 hrs.
So, The circumference of earth is (1000 mi/hr)*24= 24000 miles
c.) Here the circumference =2*pi*radius
So, The radius of earth is = 24000 miles/(2*pi)= 3822 miles
