Answer:
because of the idea that like charges get repulsion as a force.
Explanation:
because you wrap the ball with foil, the negative charges will leave the foil and go into the ball by induction. This leaves the foil as a positively charged particle since its electrons left it for the ball, making the ball a negatively charged particle. but if you bring the negative charge near the foil, the electrons will transfer from that and go into the foil, making it negatively charged. Now, because the ball and the foil have the same charge, they repel. the foil flies off.
Answer:
N₂= 697.24 m/s,
O₂= 652.38 m/s
CO₂= 393.35 m/s
Explanation:
The rms speed, of a gas is the following:
<em>where R: is the ideal gas constant, T: is the temperature and M: is the molar mass. </em>
<u>Knowing that the molar mass of the given gases are:</u>
N₂ = 14.0067 g/mol = 14.0067x10⁻³ kg/mol
O₂ = 15.999 g/mol = 15.999x10⁻³ kg/mol
CO₂ = 44.009 g/mol = 44.009x10⁻³ kg/mol
Also that T is 0 °C = 273 K, and R = 8.314 J/ K.mol = 8.314 kg.m². s⁻². K⁻¹. mol⁻¹. The rms speed of the gases are:
For N₂:
For O₂:
For CO₂:
Therefore, the rms speed of N₂ is 697.24 m/s, of O₂ is 652.38 m/s and of CO₂ is 393.35 m/s
