They play a big part in convictions but you can’t convict someone just from a witness statement *usually* it has happened before although it is rare.
Answer:
Explanation:
Ductile materials typically have a higher ultimate strength because they stretch absorbing more energy before breaking. While fragile materials snap in half before larger deformations due to larger loads occur.
It should be noted that when ductile materials stretch their section becomes smaller, and in that reduced section the stresses concentrate.
Answer:
Dimension of specific heat will be ![=L^2T^{-2}\Theta ^{-1}](https://tex.z-dn.net/?f=%3DL%5E2T%5E%7B-2%7D%5CTheta%20%5E%7B-1%7D)
Explanation:
We know that heat
, Q is heat generated, m is mass, c is specific heat and
is temperature difference
From formula we can write ![c=\frac{Q}{m\times \Delta T}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7BQ%7D%7Bm%5Ctimes%20%5CDelta%20T%7D)
Now unit of Q is joule or N-m
Newton can be written as ![kgm/sec^2](https://tex.z-dn.net/?f=kgm%2Fsec%5E2)
So unit of Q is ![kgm^2/sec^2](https://tex.z-dn.net/?f=kgm%5E2%2Fsec%5E2)
For dimension we use M for kg, L for meter(m) ,T for sec and
for temperature
So dimension of Q is ![ML^2T^{-2}](https://tex.z-dn.net/?f=ML%5E2T%5E%7B-2%7D)
So dimension of specific heat will be ![\frac{ML^2T^{-2}}{M\Theta }=L^2T^{-2}\Theta ^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7BML%5E2T%5E%7B-2%7D%7D%7BM%5CTheta%20%7D%3DL%5E2T%5E%7B-2%7D%5CTheta%20%5E%7B-1%7D)
Answer:
the curve will flatten due to the supply and demand theory.
