Explanation:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength.
Some metals having unpaired electrons contain a strong magnetic response, i.e, they can be magnetized by an external magnetic field.

I will GUESS that we're supposed to be looking at a plot of a position in time.
IF that is the case.
THEN the answer would be Point B because it has the steepest slope.
0.495 m/s
Explanation
the formula for the terminal velocity is given by:
m is the mass
g is 9.81 m/s²
ρ is density
A is area
C is the drag coefficient
then
Step 1
Let's find the mass
now, replace
hence, the answer is 0.495 m/s
