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)?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
