Calculating if the average or normal temperature decrease with altitude in the troposphere is 6.5°c/km, calculate the approximate altitude in which a pilot would expect to find each of the following atmospheric temperatures, if the surface temperature is 27°c. show your work. 10°c: meters 0°c: meters

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

this could be newton#'s law of cooling. the cooling curve is exponential

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
