Hey SDNers,
I have come across question 49 on AAMC practice test 5 which I am having difficulty understanding the concept and problem set up. The explanation provided from AAMC is vague while that of Kaplan is too long.
It would be helpful if anyone can help me understand how to set this problem up. Plus this question was similar to a problem in AAMC #4 question 18. Any help would be apprecaited!
The question is:
An object that is totally immersed in benzene (specific gravity of 0.7) is subject to a buoyancy force of 5N. When the same object is totally immersed in an unknown liquid, the buoyancy force is 12N. What is the approx specfic gravity of the unknown liquid?
a)0.3
b)0.9
c)1.7
d) 2.3
ans is c.
AAMC 4, question 18:
An object of 15 grams is immersed in benzene and suffers an apparent weight loss of 5 grams. What is the apprx specfic gravity of the object? (specifc gravity benzene 0.7)
a)1.4
b)1.8
c)2.1
d)3.0
ans c
