The answer for this would be B!!
Answer:
low risk for tissue damage
uses radio waves
the last three are not correct
:)
The object will not be able to accelerate perpendicular to direction of motion
Answer:
C = 1.01
Explanation:
Given that,
Mass, m = 75 kg
The terminal velocity of the mass, 
Area of cross section, 
We need to find the drag coefficient. At terminal velocity, the weight is balanced by the drag on the object. So,
R = W
or

Where
is the density of air = 1.225 kg/m³
C is drag coefficient
So,

So, the drag coefficient is 1.01.
