Answer:
1.5 m
Explanation:
Step 1: Given data
Maximum speed recorded for a giant tortoise (s): 0.11 m/s
Time elapsed (t): 6.0 h
Step 2: Convert "s" to mi/h
We will use the following conversion factors:
- 1 mi = 1609.34 m
- 1 h = 3,600 s
![\frac{0.11m}{s} \times \frac{1mi}{1,609.34m} \times \frac{3,600s}{1h} = 0.25m/h](https://tex.z-dn.net/?f=%5Cfrac%7B0.11m%7D%7Bs%7D%20%5Ctimes%20%5Cfrac%7B1mi%7D%7B1%2C609.34m%7D%20%5Ctimes%20%5Cfrac%7B3%2C600s%7D%7B1h%7D%20%3D%200.25m%2Fh)
Step 3: Calculate the distance traveled (d) by the giant tortoise
We will use the following expression.
s = d/t
d = s × t
d = 0.25 m/h × 6.0 h
d = 1.5 m
Answer:
The symbol that represent a salt is CaCl2
Explanation:
The CaCI2 is the calcium chloride that an organic compound now a salt having a chemical formula i.e. CaCI2. Also it is non-color cyrstalline solid at the room temperature also it is highly soluble in the water
