What is the length of an aluminum rod at 65 degress celcius if its length at 15 degrees celcius is 1.2 meters?
You can get the coefficent of linear expansion for aluminum from your text or a handbook.
I don't understand, can someone else help me? Thank You.
what happens when a negatively charged object and a positively charged object are brought together
the answer to your first question is c. 1.201386 meters
When a negatively charged object and a positively charged object are brought together, several things can happen depending on their relative charge and the materials involved. Here are a few possible scenarios:
1. Attraction: If the negatively charged object and the positively charged object have opposite charges, they will be attracted to each other. This is because opposite charges attract each other due to the electrostatic force.
2. Repulsion: If both objects have the same type of charge (either both positive or both negative), they will repel each other. Like charges repel each other due to the electrostatic force.
3. Neutralization: If the negatively charged object has a higher magnitude of charge than the positively charged object, bringing them together can result in neutralization. This means that some of the excess charge may transfer between the objects, causing both to become neutral or less charged.
It's important to note that the specific behavior between the objects will depend on factors such as the magnitude of their charges, the distance between them, and the materials involved.
