At 28 degrees highest line is CaCl2. Answer a.
Answer:
Substance 4
Explanation:
Density is defined as mass per unit volume. A substance floats in another when its density is less than that of the substance on which it floats.
If an object is immersed in a denser liquid, it will sink
Since the density of water is 1 g/cm^3, any substance whose density is less than that of water will float in it.
If we look at the table, substance 4 has a density of 0.5g/cm^3. Hence, substance 4 is expected to float in water.
The increase of angles between two bones is and ankle
Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333
A.) 23mi/hr
B.) 22.20mi/hr
