Answer: (b) Approximately 32 years
.
Explanation:
Moves = 2n-1
.
It takes (224-1) are the minimum number of moves required to move 24 disks, which is 16777216.
Now each move takes 1 minute, therefore total time in (mintes) = 16777216
.
Now in one year we have 525600 minutes.
Therefore time in years = 16777216/525600 = 31.920121765601217656012176560122 = 32 years (approx)

Responda:
9.2s
Explicação:
Dada a pergunta:
Em quanto tempo o um paraquedista, em queda livre, atinge a velocidade de 90 m / s?
Em queda livre; a aceleração de um corpo = 9,8m / s ^ 2
Portanto, quanto tempo leva para atingir uma velocidade de 90 m / s
Da primeira equação de movimento:
v = u + em
v = velocidade final; u = velocidade inicial; a = aceleração; t = tempo
90 = 0 + 9,8t
90 = 9,8t
t = 90 / 9,8
t = 9,18s = 9,2 s
