Why does aluminum expand more than copper

Physics
2 answers:
lapo4ka [179]3 years ago

It expands more because some metals expand more than others due to differences in the forces between the atoms / molecules. In metals such as iron the forces between the atoms are stronger so it is more difficult for the atoms to move around . In brass the forces are a little weaker so the atoms are free to move about more. Same for aluminum and copper. Hope this helps.

<h3>For common materials like many metals and compounds, the thermal expansion coefficient is inversely proportional to the melting point. Copper’s melting point is less than iron’s, so its thermal expansivity is greater.</h3>

At higher speeds, how would you compensate for the decrease in field of vision
inysia [295]
When you ride a vehicle in a fast speed, then your peripheral vision will reduce that is why there is a need for you to follow the direction of the objects when you are travelling in order for you to compensate to the decrease in the field of vision.

Which statement correctly differentiates between transmitters and receivers?
jeka94

Answer:

Transmitters send radio waves, and receivers capture radio waves.

Explanation:

Let us look at each of the choices one by one:

(1).Transmitters have antennas, and receivers do not have antennas.

Nope. To send signals transmitters need antennas, and to receive signals   the receivers need antennas as well.

(2). Transmitters send radio waves, and receivers capture radio waves.

This is true. Transmitters are for transmitting and receivers are for     receiving EM signals.

(3). Transmitters have demodulators, and receivers have modulators.

No, it is the other way around. Transmitters have modulators, and          receivers have demodulators.

(4). Transmitters do not have amplifiers, and receivers have amplifiers.

Nope. Both the transmitters and the receivers need amplifiers.    Transmitters need them to increase the power of the broadcast, and   receivers need them to amplify the signal for processing.

Therefore, only the 2nd statement "Transmitters send radio waves, and receivers capture radio waves." is correct.
