Sound travels 10200m farther through stone in 17 seconds than through aluminium

Speed of sound in aluminium = 3100 m/s

The speed of sound in stone = 3700 m/s

Time taken = 17 minutes

Distance traveled = Speed x Time

Distance traveled by sound in aluminium in 17 seconds = 3100 x 17

Distance traveled by sound in aluminium in 17 seconds = 52700 m

Distance traveled by sound in stone in 17 seconds = 3700 x 17

Distance traveled by sound in stone in 17 seconds = 62900 m

Difference in the distance traveled = 62900 - 52700

Difference in the distance traveled = 10200 m

Sound travels 10200m farther through stone in 17 seconds than through aluminium

In 2004, it was reported that "the relationship between body mass, M, and standard metabolic rate, B, among living organisms rem

lesya692 [45]

The answer is 8884.37 times

In many cases, B is approximately proportional to the three-quarters power of M:
 $B= M^{3/4}$

Elephant:
M1 = 4.6 mt = 4.6 * 1,000,000 g = 4,600,000 g
 $B1= 4600000^{3/4}=99327.24$

Mouse
M2 = 25 g
$B2= 25^{3/4}=11.18$

determine how many times greater the metabolic rate of an elephant is than that of a mouse:
B1/B2 = 99327.24 / 11.18 = 8884.37 times
