A hollow conductor is positively charged. Asmall uncharged metal ball is lowered by a silk thread through asmall opening in the
top of the conductor and allowed to touch itsinner surface. After the ball is removed, it will have_____________. a. a positive charge
b. a negative charge
c. no appreciable charge
d. a charge whose sign depends on what part of the innersurface it touched
e. a charge whose sign depends on where the small hole islocated in the conductor
According to the property of a conductor, the entire charge will reside on the outer surface of the conductor, there is no charge on the inner side of the conductor. As the uncharged metal ball touches the inner surface of the conductor, it does not attain any charge as the inner side of the conductor has no charge.
Ozone gas is made up of oxygen molecules that have three atoms. it exists in polluted air and ozone layer. Ozone layer is formed in stratosphere(part of atmosphere).
There are two forces acting on a rocket at the moment of lift off: Thrust pushes the rocket upwards by pushing gases downwards in the opposite direction.Weight is the force due to gravity pulling the rocket downwards towards the centre of the earth.So I'm thinking the answer is THRUST.
