Diclofenac Patches are considered one of the
major transdermal patches
used as a pain killer. If the
patch was of circular shape
with radius of 2cm and the
thickness of the patch was
100 micro meter. The
release of diclofenac from
this dosage form showed a
lag time of 8.5 min.
calculate the total amount
of Diclofenac (mg) released
from the patch after 6hours,
if the concentration inside
the patch was 12.5mg/ml,
knowing that the partition
coefficient of the drug at
25°C is 10.5.
Select one:
a 326 mg
b. 112 58 mg
C. 107.56​

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
