How is grounding a positive object different from grounding a negative object?
Natali5045456 [20]

Answer:

Grounding a Positively Charged Object

Electrons were transferred from the electroscope to the ground. As in the case of grounding a negatively charged electroscope, the grounding of a positively charged electroscope involves charge sharing. The excess positive charge is shared between the electroscope and the ground.

If an earthquake occurred in Miami, Florida, then how long would it take for a seismic station in Seattle, Washington, to pick u
Juliette [100K]

0.017s

Explanation:

Given parameter

Distance = 5000km = 5 x 10⁶m

Unknown:

time taken = ?

Solution:

We use the normal speed equation to solve this problem as we take the speed of the wave to be 3 x 10⁸m/s.

   Speed = \frac{Distance }{Time taken}

   Inputting the parameters:

             Time taken = \frac{distance }{velocity of the wave}

  Time taken = \frac{ 5 000000}{3 00000000} = 0.017s

Explain why materials such as plastic foam, feathers, and fur are poor conductors of heat.
Firlakuza [10]
The atoms of some materials have no free electrons in their outer orbits. These electrons are busy doing other jobs, like being shared in the orbits of two adjacent atoms. They are so closely held that it is very difficult to pull them away. Most compounds of carbon and hydrogen are like this. 

<span>Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity (and they are also poor conductors of heat). hope that helped.</span>
