Answer:
conductor
Explanation:
A "conductor" is a material that allows the charges to pass freely from one body to the other. This causes a movement among the electrons and this means that<em> the charge will be passed entirely to the object receiving it.</em> This is also called <em>"conductive material."</em>
Examples of conductors are: <em>copper, aluminum, gold, silver, seawater, etc.</em>
The opposite of conductors are called "insulators." These do not allow the free movement of charges from one object to the other.
Examples of insulators: <em>plastic, rubber, paper, glass, wool, dry air, etc.</em>
Answer:
we can see that this time period is independent of the mass of the child so answer would be same if the child mass is different
Explanation:
Natural frequency of a simple pendulum of L length is given as
so the time period of the oscillation is given as
so we will have
also from above formula we can see that this time period is independent of the mass of the child so answer would be same if the child mass is different
