Explanation:
its hard to explain its very complex but its so they can function properly
Answer:
In the middle of a dry cell, is a rod made of carbon. Around the carbon rod is a chemical paste. At the same time, the carbon rod becomes positively charged. When this happens, electrical current flows out of the cell when a conductor is attached between the cell's positive and negative terminals.
Answer: The sound will change due to changes in frequency and the wavelength of the airplane.
Explanation: Let assume that the observer is at a stationary position. The wavelength of the sound from the airplane reduces and the frequency increases as the plane is moving toward the observer. As the airplane passes by, that is, moving away from the observer, the frequency starts to reduce while the wavelength of the sound starts to increase.
The sound that the observer hears will change base on the illustration above.
False, as an object falls its potential energy turns into kinetic energy thus decreasing the potential energy.
Answer:
It will float.
Explanation:
Hello.
In this case, given the width, length and height, we can compute the volume as follows:
Moreover, since the density is computed via the division of the mass by the volume:
We obtain:
In such a way, since the solid has a lower density than the water, we infer it will float.
Best regards.
