A thin rectangular coil 2 cm by 7 cm has 60 turns of copper wire. It is made to rotate with angular frequency 104 rad/s in a magnetic field of 1.7 T. (a) What is the maximum emf produced in the coil?
(b) What is the maximum power delivered to a 40 ohm resistor?

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?
