Four very lightweight disks of equal radii each have three identical heavy marbles glued to them as shown in the figure below. Rank in order, from largest to smallest, the moments of inertia of the disks about the indicated axis (shown as a black dot). Axis a) Ip> IB > Ic > IA b) Ic> IA > Ip > IB c) Ic> IB > Ip> IA d) IB > IA > Ip > Ic e) Ip> IA > Ic > IB A В C O o o A

Please answer A, B, and C.

A man runs around a circular track of 800 meters radius for 30 seconds, starting at a point directly to the right of the center and goes in a counterclockwise manner. He goes 5 meters per second for the first 15 seconds, runs 90 meters for the next 6 seconds and then 180 meters for the rest of the course. What was his average speed, his displacement from the starting point, his average velocity, and his total displacement upon return to the starting point?

Calculate the mass (in SI units) of a 140 lblb human being. Express your answer with the appropriate units.

A​ "bullet" train set a new world record for train speed at 552 kilometers per hour during a manned test run on the Test Line in April 1999. The Test Line is 42.8 kilometers long. How many minutes would a test run on the Test Line last at this​ record-setting speed?

Could you explain why 2.5 is the correct answer ?

At 9:13 A.M., a sports car is traveling 30 miles per hour. Two minutes later, the car is traveling 90 miles per hour. The mean value theorem guarantees that at some time during this two-minute interval, the car's acceleration is exactly A miles per hour squared. Compute the value of A. A = mi/h² Need Help? Read It

The arctic tern migrates farther than any other bird. Suppose the tern travels 16513 km south, only to encounter bad weather. Instead of trying to fly around the storm, the tern turns around and travels 617 km north to wait out the storm. It then turns around again immediately and flies 14814 km south to Antarctica. What is the tern's average speed in km/h if it makes this trip in 144 days? (Please round your answer to two decimal place; DO NOT include units)
