Answer:
Explanation:
For a linear elastic material Young's modulus is a constant that is given by:
Here, F is the force exerted on an object under tensio, A is the area of the cross-section perpendicular to the applied force, is the amount by which the length of the object changes and is the original length of the object. In this case the force is the weight of the mass:
Replacing the given values in Young's modulus formula:
Answer:
heat energy that is needed to raise tempeture
I think the correct answer from the choices listed above is option D. Scientific theories summarize patterns found in nature. Although, the statement scientific theories are never proven is somewhat true. They are either disproved or they are never disproved. Hope this answers the question.
Power is the rate at which energy is used in a circuit.
