Cevap
To solve this problem, we can use the equation of motion for uniformly accelerated motion:
where:-
is the displacement (the depth of the lake),-
is the initial velocity (which is 0 m/s since the bubble starts from rest),-
is the acceleration (10.0 m/s
),-
is the time (10.0 seconds).Plugging in the values, we get:
Therefore, the correct answer is:E. 500 meters
