Answer:
the answer is 32.0-25.0=7
Explanation:
the absolute pressure at the bottom of the container is 7
Answer: The pressure of the air when compressed is
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
where,
= initial pressure of gas = ![1.0\times 10^5Pa](https://tex.z-dn.net/?f=1.0%5Ctimes%2010%5E5Pa)
= final pressure of gas =?
= initial volume of gas = V
= final volume of gas = ![\frac{V}{5}](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B5%7D)
Therefore, the pressure of the air when compressed is
Measurement tools make our lives safer and better? And they increase the quality and quantity of life. Arguably, the ability to measure calculating
physical properties accurately have tremendous survival value that gives humans adaptive, evolutionary advantages sharpened through many years of natural selection.
Answer:
2 m/s
Explanation:
...........................
Metal is conductive, so electrons will transfer onto sphere b until there is an equal number of electrons on either sphere (the electrical gradient will be zero). This means that 5 x 10^11 electrons will be on either sphere, and since the charge of an electron is 1.602 x 10^-19 Coulombs, multiplying this by the number of electrons gives a charge of 8.01 x 10^-8 Coulombs, or 80.1 nanocoulombs.
