A scientist is studying an organelle that is controlling the amount and types of substances that are moving in and out of a cell. She is observing the

a.) is the correct answer.

explanation:

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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
