Answer:
1)diaphragm vibrations- sound waves
2) Changing magnetic fields- Electrical energy
3)sound waves- Mechanical energy
Explanation:
A changing magnetic field induces an electromotive force and then an electric field which contains electrical energy
Sound energy is a form of energy that can be heard by humans. Sound is an example of a mechanical wave because it consists of physically oscillatory elastic compression.
A diaphragm is a thin surfaced cone used to produce sound. It is caused to vibrate using electromagnetic energy.
Answer:
Option A, Ohio River and the Missouri River
Explanation:
The historical evidences clearly indicate that Ohio River did not exist before the last ice advances. Before Ohio and Missouri river, the major glacier drainage of the east-west direction happens in Teays River. When ice of the glaciers blocked the Teaya river valley, then the Ohio was formed.
Like Ohio, Missouri river did also not exist before Pleistocene and during that time the largest drainage in North America take place in the Hudson's Bay
Hence, option A is correct
Energy input would be what's giving the source energy. Energy output is what energy it's giving out.
