This sites states that if you were to fold a piece of paper 30 times, it would reach a thickness of 6.67 miles (average height of a moving plane).
If we fold it 45 times, the thickness is now over 250,000 miles and the distance between earth and moon is around 239,000 miles.
There is a theory that folding a piece of paper (large enough, with enough effort acting on it) 42 could reach the moon. Theoretically, it's only possible to fold a piece of paper 8 times, but when you do this, measure the width of the growing paper. Each time it's folded, the paper doubles in size.
Eventually, the paper will start grow faster (quicker) because the number is getting larger too. It would logically be impossible, but as a theory it stands as a possibility
Answer:
24 hours
Step-by-step explanation:
160 x 18 = 2880
2880/120 = 24
Answer:
The rate of change in the submarine's elevation is 26.0 feet per second.
Step-by-step explanation:
She begins 151 feet below sea level
Thus, her initial point is y₁ = 151 feet below sea level
i.e. at t₁=0 seconds, y₁ = 151 feet below sea level
After descending for the 3 seconds, she is 229 feet below sea level.
Thus, her second point is y₂ = 229 feet below sea level after 3 seconds
i.e. at t₂=3 seconds, y₂ = 229 feet below sea level
The rate of change is basically the slope. Thus, the rate of change can be obtained by taking the slope.
slope = rate of change = (y₂ - y₁)/(t₂ - t₁)
= (229 - 151) / (3 - 0)
= 78/3
= 26.0
Therefore, the rate of change in the submarine's elevation is 26.0 feet per second.
