4. A rock is suspended from a string; and it accelerates downward. Which one of the following statements concerning the tension in the string is true? * O The tension points downward. O The tension is less than the weight of the rock. The tension is equal to the weight of the rock. O The tension is greater than the weight of the rock. The tension is independent of the magnitude of the rock's acceleration.
