Answer:
Energy by definition is the property of matter that involves interactions with molecules, in order to perform an action.
Explanation:
They're many different types of energy, a few of them are...
. Thermal energy
. Solar energy
. Chemical energy
. Kinetic energy
. Potential energy
. Mechanical energy to name a few...
All of these specific energies involve the interaction of molecules which are used for different things and can be converted from one type of energy to another.
Hope this helps.
Answer:
10.66mm
Explanation:
Given that the elongation is
and Length,
and Tensile Strength,
, The longitudinal stress can be calculated as:
![\epsilon=\frac{\bigtriangleup l}{l}=0.11/63=1.746\times10^-^3](https://tex.z-dn.net/?f=%5Cepsilon%3D%5Cfrac%7B%5Cbigtriangleup%20l%7D%7Bl%7D%3D0.11%2F63%3D1.746%5Ctimes10%5E-%5E3)
The value of strain-stress,
corresponding to
'
![\sigma=\frac{F}{A_o}\\150=\frac{53500}{\pi r_o^2}\\\\r_o=10.66mm](https://tex.z-dn.net/?f=%5Csigma%3D%5Cfrac%7BF%7D%7BA_o%7D%5C%5C150%3D%5Cfrac%7B53500%7D%7B%5Cpi%20r_o%5E2%7D%5C%5C%5C%5Cr_o%3D10.66mm)
Hence, the radius of the specimen is 10.66mm

The size of the field 'decreases'. Imagine zooming in on your TV so that your face is pressed up against the screen. you can see the individual pixels but you cannot see the whole picture because the sizer of your 'field of view' has shrunk.
