السلام عليكم اخواي هذا سؤال في مادة الفيزياء الرياضية اذا ممكن تساعدوني فيه؟؟
the rate of evaporation from a particular spherical drop of liquid (constant density) is proportional to its surface area.Assuming this to be the sole mechanism of mass loos find the radius of the drop as a function of time.
