Please help! A straight wire is placed in the magnetic field of a U-shaped magnet as shown in fig. 1 (attached) The length of the wire in the field is 35 mm. When a current of 1.8 Amp is in the wire, a force of 0.024 N acts on the wire due to the field. Calculate the magnetic flux density of the field. Thank you for helping (if you can!)

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?
