If a negatively charged rod touches a conductor, the conductor will be charged by what method?

a: induction
b: friction
c: convection
d: conduction

b friction

thanks for the points

D. conduction

Explanation:

Charge is transferred from one object together by mainly three methods:

1. Induction: when a charged object is brought close to an uncharged object, the charge is induced.

2. Friction: when two bodies having different electro-negativity are rubbed against each other, both of them get charged. For example, balloon when rubbed with fur.

3. Conduction: when a charged object is touched to an uncharged object, the uncharged object gets charged.

Thus, when a negatively charged rod touches a conductor, the conductor would be charged by conduction.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
