Asolution contains equal amounts of ammonia and ammonium chloride, and is buffered at a ph of 9.25. which action will most strengthen the buffering capacity at this ph?

Doubling the amounts of both ammonia and ammonium chloride is the action that will most likely strengthen the buffering capacity of a solution that contains equal amounts of ammonia and ammonium chloride, and is buffered at a pH of 9.25.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
