Liquid oxygen, which has a boiling point of 90 k and a latent heat of vaporization of 214 kj/kg, is stored in a spherical container whose outer surface is of 500-mm diameter and at a temperature of −10°c. the container is housed in a laboratory whose air and walls are at 25°c. (a) if the surface emissivity is 0.20 and the heat transfer coefficient associated with free convection at the outer surface of the container is 10 w/m2 ⋅ k, what is the rate, in kg/s, at which oxygen vapor must be vented from the system? (b) moisture in the ambient air will

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
