A straight vertical wire passes by a wooden table top. The wire carries an upward directed current. Evaluate the path of the magnetic field of the wire at a point on the table top
The argument reveling that tachyons (must they exist, of course) cannot carry an electric charge. For a (imaginary-massed) particle travelling quicker than c, the less energy the t
p1v1=p2v2 let partial pressure of helium in 30L be P then p1*30=2*10 p1=20/30 bar=2/3bar partial pressure of O2=p2 p1+p2=1bar partial pressure of O2=1/3 bar
p1v1=p2v2
let partial pressure of helium in 30L be P
then p1*30=2*10
p1=20/30 bar=2/3bar
partial pressure of O2=p2
p1+p2=1bar
partial pressure of O2=1/3 bar
