B) because 1000g= 1kg
so 6500g=6.5kg
Yes because say we are doing 2/10 if you divide 2 by 2 and 10 by 2 it will be 1/5 which equals the first one so yes they are.
By Stokes' theorem,

where

is the circular boundary of the hemisphere

in the

-

plane. We can parameterize the boundary via the "standard" choice of polar coordinates, setting

where

. Then the line integral is


We can check this result by evaluating the equivalent surface integral. We have

and we can parameterize

by

so that

where

and

. Then,

as expected.

Its the same thing because your just switching the order which doesn't matter when your adding or multiplying
