Approximately how many atoms are there in a baby elephant (mass 240 kg)? Give the order of magnitude (power of ten).

A: 18 B: 22 C: 28 D: 35 E: 44
Tries 0/1

The feet of the elephant are approximately round with a radius of 6 cm. How much average pressure does the elephant exert on the ground under its feet if it is standing on all four feet? (in kPa)

A: 52.0 B: 65.1 C: 81.3 D: 102 E: 127
Tries 0/1

The elephant has a volume of 0.23 m3. If it is taking a bath with 54 percent of its volume under water (fresh water, density 1 g/cm3), how much average pressure do its feet exert on the bottom of the pool? (in kPa)

A: 8.03 B: 10.7 C: 14.2 D: 18.9 E: 25.1
