use the provided link to answer the following

QUESTION 1 To find the angular acceleration (or )caused by the frictional torque, we will do which of the following? O Spin the platform plus disk-with handle and take of as the slope of w versus time graph. 3 Spin the platform and take of as the slope of w versus time graph. 0 Spin the platform with a hanging weight and take of as the slope of the velocity versus time graph. Q Spin the platform and take off as the slope of linear velocity versus time graph. QUESTION 2 In Part II, we will take take the uncertainty in angular velocities (w) as which if the following? The length of time between the two downward-sloped portions of an w versus time graph, multiplied by of- The length of time the hanging mass falls multiplied by of O The length of time the platform rotates once multiplied by af- O t one of the smallest divisions of the w tool. QUESTION 3 We will set a User Parameter in Logger Pro to w/2 = 1.571. What is this quantity in our experiment? The angular width of one black segment on the platform. The angular width of one black-clear segment on the platform. O The angular width of the disk-with-handle. The length of fall for the hanging mass, in meters. QUESTION 4 In Equation 2, an expression of I of the platform in terms of other quantities. Which of these is represented by "m"? The mass of the falling mass (little weight). The mass of the platform. O The mass of the disk-with-handle. O The mass of the string. QUESTION 5 We will find the moment of inertia (1) of the disk-with-handle by which method? Q Use measured quantities and Equation 2. J Calculate from first principles. " Use measured quantities and Equation 1. Direct measurement with a moment-of-inertiaometer
