Ответ:
It does not depend on intensity. Intensity of light only affects the number of electrons ejected. Threshold frequency is dependent on the type of metal . It is not determined by the incident photon . Each metal has its own threshold frequency. So the most feasible answer is d.
Ответ:
In short, Your Answer would be Option D
Hope this helps!

Definition
Acceleration is the term used to describe an object that is either speeding up or slowing down.
Explanation
Based on the given answer choices, answer choices A, C, and D does not describe an object either gaining speed or losing speed; however, object B states this. For this reason, answer choice B is the correct answer.
Answer
b. ac car slowing down on a sharp curve
