How can I solve these? 1) How many turns of wire would be required to make a 160-mH inductor out of a 32.0-cm-long air-filled solenoid with a diameter of 6.3 cm ? N = turns

2) When a car drives through the Earth's magnetic field, an emf is induced in its vertical 55-cm-long radio antenna. What is the maximum emf induced in the antenna? The car's speed is 30.0 m/s on a horizontal road, the Earth's field is (5.0×10^−5 T), and the dip angle of 38 degrees. ε =

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?

If the radius of curvature of the cornea is 0.75 cm when the eye is focusing on an object 36.0 cm from the cornea vertex and the indexes of refraction are as described before, what is the distance from the cornea vertex to the retina? express your answer to two significant

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
