Assuming that ‘theta’ refers to an angle measured between the string and a vertical line (extending from the pendulum’s pivot point down toward the center of the earth), which of the following statements is/are typically found to be TRUE (Select ALL that apply)? T, the tension exerted by the string onto the pendulum bob, and mg sin (θ), a component of the bob’s weight, are directed along the same axis as each other. T, the tension exerted by the string onto the pendulum bob, and mg cos (θ), a component of the bob’s weight, are directed along the same axis as each other. mg sin (θ) is directed along the same axis as the instantaneous velocity of the bob
