A pair of diastereomers is each individually mixed with a strong base, and for both an E2 reaction occurs. Provide the missing curved arrow notation, and draw the correct geometric isomer that is formed for both of the E2 mechanisms.

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.
