Part I. Use the four diagrams below to answer some questions about torque. Each of the arrows represents a force of 50 newtons applied to the edge of a wheel. Each wheel can rotate around an axis located at the center of the wheel and pointing in and out of the page. The radius of each wheel is 0.1 meter. Answer A, B, C, D, or none to each question. 1. Which wheel will not rotate at all when...

QUESTION 22 A horizontal power line of length = 58.0 m carries a current of 1 = 2.20 kA northward as shown in th figure. The Earth's magnetic field at this location has a magnitude of B = 5.00.1051. The field at this location is directed toward the north at an angle = 65.0" below the power tine. Find the magnitude Fand the direction of the magnetic force on the power line.

Please write legibly and write out all equations and units. Please show all steps. Algebra-based physics only please. 5. An ice skater spins on the ice with her arms tight against her body. In this position, she has a moment of inertia of 1.2 kg.m² and an angular speed of 15 rad/s. She then stretches her arms out and her angular speed slows to 6.0 rad/s. What is her new moment of inertia? A B C D E 4.2 kg.m...
