A coil with 100 turns is wound on a toroidal core as shown in Figure 5.15. The core has an inner radius of 2 cm, an outer radius of 5 cm, and a thickness of 1 cm. The core material has a uniform permeability of μ = 200 μ0 and saturates at a flux density of 1.2 T. A What is the inductance of the coil? B How much current is required to bring the core to the start of saturation (i. e. so that the material at the inner diameter of the core reaches a flux density of 1.2 T)? C How much current is required to fully saturate the core (i. e. to make all of the material in the core have a flux density of at least 1.2 T)?

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
