1
Q
Archimedes
Law of similitude
Law of buoyancy (body composition)
A
True
2
Q
FFM stands for
A
Fat free mass
3
Q
Densitometry: basic assumptions Body consists of 2 compartments Fat mass & fat free mass Density of FM =0.90 g/ml Density of FFM is approx 1.10g/ml
A
True
4
Q
How do we determine density?
A
Density =mass/volume
5
Q
What does a water displacement tank measure?
A
The volume of water displaced
6
Q
Bod pods measure the?
A
Volume of air displaced
7
Q
Fat people float, lean people sink
A
True
8
Q
What is the law of buoyancy?
A
Weight of liquid displaced
9
Q
Underwater weighing
Density=mass/volume
Volume=(Wt air-Wt water)
Density=mass/ (Wt air- Wt water)
Wt stands for weight
A
True
10
Q
Density=mass/volume
Volume= (Wt air - Wt water) / water
(Minus the entrapped volumes in the lungs and GI tract)
A
True
