Answer 1

1. A motor is an electrical machine which converts electrical energy into mechanical energy. The principle of working of a DC motor is that "whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force".

2. Key actions of adrenaline includeincreasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).

Answer 2

electromagnetic induction
and adrenaline is like a emergency hormone it gets secreted when body feels it is in danger
hope it helps
