Answer:
Speed is a measure of how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time.
When heat is applied to a substance/material or steel in our case, a series of changes will occur, one of which is Expansion.
Hence the hole will expand from 1cm to a diameter that is greater.
Thermal expansion refers to the expansion or contraction of the dimensions of the solid, liquid or gas when their temperature is changed.
<h3>Types of Expansion</h3>
- Linear expansion
- Areal expansion and
- Volumetric volume.

Answer:night
Explanation:At night , the air is denser due to humidity (obviously nights are cooler). sound requires medium to travel and so DENSER the medium,FASTER the sound travels. Humid air is denser than warmer air as in day.
There simple rules for series and parallel circuits.
For the series circuits we have the following rules:
1)The same current flows through each part of a series circuit.(<span>I = I1 = I2 = I3)
2)</span>The total resistance of a series circuit is equal to the sum of individual resistances.(<span>Req = R1 + R2 + R3)
3)The</span> voltage applied to a series circuit is equal to the sum of the individual voltage drops.(<span>V = V1 + V2 + V3)
</span>For the parallel circuits we have the following rules:
1)Voltage is the same across each component of the parallel circuit.(<span>: V = V1 = V2 = V3)
</span>2)The sum of the currents through each path is equal to the total current that flows from the source.(<span> I = I1 + I2 + I3)
3)The total resistance is equal to the sum of the reciprocal value of individual resistors in the circuit.
The x region represents the series circuit. The y region represents a combination of series and parallel circuit. This means that for y region we can apply laws for both series and parallel circuits.
So, all the equation can be applied to the y region.
However, not all equation can be applied to the x region. We can apply following equation to the x region:
1)</span><span>I = I1 = I2 = I3
</span>2)<span> V = V1 + V2 + V3
3)</span><span>Req = R1 + R2 + R3</span>
Answer:
Elastic potential energy store - which is the energy transferred to a spring as it's stretched.
