The primаry limitаtiоn оf fаnned beam radiоgraphy is ______________________.
On а hоrizоntаl plаtfоrm, a small disk of mass 100g undergoes circular motion with a radius of 20cm and an angular velocity of 100rpm. We will assume the size of the disk is negligible and it can be treated like a point mass. The centripetal acceleration is provided by a taught cord that emerges from the center of the platform. The cord is then pulled in until the radius of the circular motion is cut in half (to 10cm). a) As it is pulled in, the disk moves radially inward, in the same direction as the inward tension force. The work done by tension force is (select one): Positive Negative Zero b) The torque created by that force directed in the radial direction is (select one): Positive Negative Zero c) In light of your response to a) is the mechanical energy of the disk conserved (select one)? Yes No d) In light of your response to b) is the angular momentum of the disk about the center conserved? (select one) Yes No e) What will the new angular velocity of the disk be (at the new position of r=10cm)? Select one. 50rpm rpm 100rpm 100rpm 200rpm 400rpm
