Indicate which of the following statements are correct. an unstable atmosphere: (a) causes turbulence to be damped; b) usually results in a vertical profile of the horizontal wind velocity that is more uniform tharn that of a stable atmosphere; causes the mean horizontal wind velocity to be larger (on a regional scale) than that ofa neutral atmosphere; (c) (d in the surface layer is favorable to disperse the pollutants; (e) is likely to be found over a deep lake in the spring, when warm air blows over the water

b.a device that inputs heat into a cool object

  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.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
