Answer:
a_s=4.8\times 10^{-2}~m^2
Explanation:
Given:
cross-sectional area of the bone, a=4.8 \times 10^{-4} ~m^2
the factor of up-scaling the dimensions, s=10
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled-up area is:
a_s=a\times s^2
a_s=[4.8 \times 10^{-4}]\times 10^2
a_s=4.8\times 10^{-2}~m^2
At the start, each can holds
• 5 L can : 0 L of oil
• 3 L : 0 L
Fill up the 5 L can completely:
• 5 L : 5 L
• 3 L : 0 L
Pour as much of the oil from the 5 L can into the 3 L can. This leaves you with
• 5 L : 2 L
• 3 L : 3 L
Empty the 5 L can:
• 5 L : 0 L
• 3 L : 3 L
Transfer the 3 L of oil into the 5 L can:
• 5 L : 3 L
• 3 L : 0 L
Fill up the 3 L can again:
• 5 L : 3 L
• 3 L : 3 L
Transfer as much of the oil as possible from the 3 L can into the 5 L can:
• 5 L : 5 L
• 3 L : 1 L
Empty the 5 L can:
• 5 L : 0 L
• 3 L : 1 L
Again, transfer the oil from the 3 L can to the 5 L can:
• 5 L : 1 L
• 3 L : 0 L
Fill up the 3 L can completely:
• 5 L : 1 L
• 3 L : 3 L
Transfer all the oil from the 3 L can to the 5 L can:
• 5 L : 4 L
• 3 L : 0 L
35% / 8 = 4.375% per minute 100-35= 65 65/4.375 = 14.8571429 It would take about 15 more minutes.
