Final answer:
The small egg will break entirely when dropped from a height of 5 meters onto the 1-inch foam.
Therefore the correct answer is option B When dropped from 5 meters.
Step-by-step explanation:
To determine from which height the small egg broke entirely when dropped onto the piece of 1-inch foam, we need to consider the impact force on the egg. The foam can absorb some of the energy from the impact, preventing the egg from breaking. However, if the height is too high, the impact force can overcome the foam's ability to absorb the energy, resulting in the egg breaking.
From the given options, we can eliminate options a and c because 1 meter and 10 meters are likely too low and too high, respectively, for the egg to break when dropped onto the foam. Option d, stating that the egg never broke when dropped onto the 1-inch foam, is incorrect because the question assumes the egg does break. Therefore, the correct answer is option b: When dropped from 5 meters. This height likely generates enough impact force to break the small egg when it hits the foam.
It's essential to note that the exact height at which the egg breaks would depend on various factors such as the strength of the foam and the fragility of the eggshell.
