A spacecraft in outer space increases its velocity by firing its rockets. How can hot gases escaping from its rocket engine change the velocity of the craft when there is nothing in space for the gases to push against?
The Henry's law constant at 25°C for carbon dioxide dissolved in water is 1.65×10^3 atm. If a carbonated beverage is bottled under a CO2 pressure of 5.0 atm: (a) Calculate the number of moles of carbon dioxide dissolved per liter of water under these conditions, using 1.00 g cm^-3 as the density of water. (b) Explain what happens on a microscopic level after the bottle cap is removed.
If a moving charged particle is deflected sideways in some region of space, can we conclude, for certain, that B→≠0\overrightarrow{\mathbf{B}} \neq 0B=0 in that region? Explain.
