Answer:
Explanation:
Regardless of the initial velocity of the pebble, the acceleration of the pebble is equal to the gravitational acceleration which is equal to 9.8 m/s2 towards downwards direction.
This can be shown by Newton's Second Law. According to the law, the net force applied on an object is equal to mass times acceleration of that object.
During the downward motion, the only force acting on the pebble is the gravitational force, hence its acceleration is equal to gravitational acceleration.
Answer:9.34 A/s
Explanation:
Given
radius of solenoid
Emf induced
no of turns per meter n=450
we know Induced EMF is given by
Magnetic Field is given by
thus
Area of cross-section
where
solving integration we get
where r=distance from axis
R=radius of Solenoid
