] My Library RedShelf D Python Programmingx her.edu/courses/4995/quizzes/3219/take DQuestion 3 10 pts Consider a car at rest. We can conclude that the downward gravitational pull on the car and the upward contact force of Earth on it are equal and opposite because the two forces form an action-reaction pair O the net force on the car is zero. neither of the above. do not have enough information to answer this question. Question 4 10 pts An object is held in place by friction on an inclined surface. The angle of inclination is increased until the object starts moving. If the surface is kept at this angle, the object O speeds up. O none of the above. O moves at uniform speed. O slows down

Explanation / Answer

(3) The force are equal because the net force in the vertical direction is zero.
hence the correct option is B.
i,e the net force on the car is zero.
(4) It will speed up because of the gravity force provide acceleration to the object.
hence the correct option is A i.e Speeds up.
