answer wuestion 1 and 2 please

In a freshman physics class, objects in free fall are often treated as though air resistance is Select one: Oa. is increasing in value. Ob. ignored and assumed to be zero. Oc. is decreasing in value. O d. is a nonzero constant of the motion. An object is undergoing free fall (neglecting air resistance). Its speed is: Select one: O a. changing by 9.8 m/s each second. Ob. a constant of the motion. O c. always increasing by 9.8 m/s each second. O d. always decreasing by 9.8 m/s each second.
