The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.

Un conductor circula por una carretera en una velocidad de 90 km/h y b que se enciende la luz amarilla de un semáforo situado una distancia de 150 m. si el semáforo tarda tres segundos en cambiar a rojo el coche frena con una aceleración de 2 m por segundos 2¿ cometer una infracción ese conductor?
