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.

To solve this problem, apply the concepts related to the calculation of the work performed according to the temperature change (in an ideal Carnot cycle), for which you have to:

Where,
C = Heat capacity of the Brick
= Cold Temperature
= Hot Temperature
Integrating,

Our values are given as


Replacing,



Therefore the work perfomed by this ideal carnot engine is 58kJ
'Ampere' is the unit of current. That's the rate at which
electrons travel in the circuit ... the number of electrons
every second. If you wanted the actual amount or number
of electrons, you'd need to know the length of time too.
It doesn't matter whether we're talking about a parallel or
series circuit.
Answer:
low sound waves like bass pass through walls better
Explanation:
Answer:
B. 7
Explanation:
Fluorine has 7 valence electrons in its orbitals.
The valence electrons are electrons in the outermost shell of an atom. Every element has a certain amount of valence electrons.
- Fluorine belongs to the 7 - group on the periodic table.
- Every element in this group has 7 electrons in their outermost shell.
- The elements in the group are called halogens.
- Other elements in this group are fluorine, chlorine, bromine, iodine and astatine.
