While conducting a lab, a physics student tried to charge different objects. she notices that the first object, caused the electroscope to deflect greatly and the second object did not deflect the electroscope at all. which of the following can she conclude about the two objects? select all that apply. object 1 is an insulator and object 2 is a conductor. object 1 is a conductor and object 2 is an insulator. object 1 could be rubber and object 2 could be copper. object 1 could be copper and object 2 could be rubber. object 1 could be used to connect a circuit together. object 2 could be used to connect a circuit together.

Option 2 Object 1 is a conductor and object 2 is an insulator.

Option 4 Object 1 could be copper and object 2 could be rubber.

Object 5 Object 1 could be used to connect a circuit together.

Explanation:

An electroscope is a device that is used to identify and measure that whether the given object carries or bear a current or not.

First object deflects the electroscope which means it carries the current and only a conductor can carry a current. Thus, the first object must be a conductor.

On the other hand second object do not deflects the electroscope which means it does not carries the current and hence it is an insulator.

Copper is a conducting material  while rubber is a non conducting material. Also a conducting material is used to connect a circuit.

Thus, option 2, 4, 5 are correct.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
