Answer:
The mass of a 5-year-old child is 20 kg. We can express this mass in scientific notation as:
2 x 10^1 kg
To find approximately how many times larger an elephant is than a 5-year-old child, we need to know the mass of an elephant. According to National Geographic, an average elephant can weigh between 2,700 and 6,000 kg. Assuming an average weight of 4,350 kg for an elephant, we can calculate the ratio of elephant mass to child mass as follows:
4,350 kg / 20 kg ≈ 218
Therefore, an elephant is approximately 218 times larger than a 5-year-old child in terms of mass.
To determine approximately how many water drops equal the mass of a child, we need to know the mass of a single water drop. This can vary depending on the size of the drop and the substance it is made of. However, for the purposes of estimation, we can assume that the mass of a water drop is approximately 0.05 grams.
