Ans: 50m per sec
Explanation:
Speed= distance / time
therefore speed = 100m/2sec
=50m per sec
Answer: Temperature and number of moles are the conditions which remain constant in Boyle's law.
Explanation:
Boyle's law states that at constant temperature the pressure of a gas is inversely proportional to the volume of gas.
Mathematically, it is represented as follows.
As equation for ideal gas is as follows.
PV = nRT
And, at constant temperature the pressure is inversely proportional to volume which also means that number of moles are also constant in Boyle's law.
Thus, we can conclude that temperature and number of moles are the conditions which remain constant in Boyle's law.
Answer:
There’s a high need for energy storage and are very expensive. Renewable energy is also not always available because some need sun while others need wind.
Explanation:
<span>C. C6H12O6
</span>This compound is covalent, and all salts are ionic compounds.
Density is g/cm^3 so you get the volume of the block:
4.6×5.5×8.4= 212.52cm^3
Then you take grams÷cm^3:
