Answer:
The last answer would be correct because if you have ever done it before you would know that rubbing your feet (just like the rubbing of ice crystals) on the carpet will create the energy you need, then once you touch the metal it creates that spark!
Explanation:
hoped that helped-I would be thankful for brainliest ;)
Answer:
Explanation:
Using the Ideal Gas Law we have and the number of moles n could be expressed as , where m is the mass and M is the molar mass.
Now, replacing the number of moles in the equation for the ideal gass law:
If we pass the V to divide:
As the density is expressed as , we have:
Solving for the density:
Then we need to convert the units to the S.I.:
Finally we replace the values:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
