The answer is A, you must repeat your experiment to ensure you results are accurate. That is the best way to know for sure and it is what you must do to every experiment.
Answer:
Explanation:
Hello there!
In this case, considering the Avogadro's gas law, which treats the volume and moles in a directly proportional way via:
Which can be solved for the final volume, V2, as shown below:
Thus, by plugging in the given data, we obtain:
Regards!
The importance of the Galapagos to Darwin theory is chances Darwin discovered several species of finches that varied from island to island .
A big part of reason it is so famous is because of Darwin finches.
which are 12 <span>species ,also the Darwin theory is only gradually accepted because people don't believe in them today</span>
Answer: See explanation
Explanation:
1. Separation of charges in an object without touching it is (charging by induction).
2. The work done moving a positive test charge between two points in an electric field divided by the magnitude of the test charge is the electric (potential difference).
3. An electric (conductor) is a material through which charges move about easily. (Charging by conduction) is giving a neutral object a charge by touching it with a charged object.
4. A material through which electrical charges does not move easily is an electrical (insulator).
5. The lines providing a picture of the size and strength of the field around a charged object are called the (electric field lines).
6. The property of the space around a charged object that exerts a force on other charged objects is the (electric field).
7. A device that helps determine charge using pieces of metal foil is an (electroscope).
8. The magnitude of the charge of an electron is the (elementary charge)
