Two spherical rain drops of equal size are falling vertically through air with a certain terminal velocity. If these two drops were to coalesce to form a single drop and fall with a new terminal velocity, explain how the terminal velocity of the new drop compares to the original terminal velocity.
Terminal velocity is directly proportional to the square of the radius of the spherical body.
Since mass is conserved and density remains same, upon coalesceing, the volumes will add up.
Thus, volume of bigger drop = 64 times the volume of each small drop. Since volume is directly proportional to cube of radius, this implies that the radius of the big drop is 4 times the radius of each small drop.
Therefore, terminal velocity of the big drop is 4 square = 16 times the terminal velocity of each small drop =1.5×16=24ms^−1
Terminal velocity is directly proportional to the square of the radius of the spherical body. Since mass is conserved and density remains same, upon coalesceing, the volumes will add up. Thus, volume of bigger drop = 64 times the volume of each small drop.
Morgan has 6 packs of erasers. Each pack of erasers has x erasers in it. After Avery gives her 3 more erasers, she has a total of 27 erasers.
