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
