They use x-rays to diagnose broken bones
Answer:Convection
Explanation:
Convection is the heat transfer procedure by the movement of liquid or gas molecules. It is a combination of diffusion and bulk motion of molecules. Near the surface of the liquid diffusion process dominates while at certain height bulk motion of liquid dominates.
Convection can be
Natural : Natural convection occurs due to density differences
Forced: Force convection occurs when we apply external heat source.
Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
<span>Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic</span>
Answer:
1028 slits/mm
Explanation:
We are given that
Wavelength of light, 
1nm=

n=1
We have to find the number of slits per mm are marked on the grating.
We know that

Using the formula



1m=
mm

Number of slits=
Number of slits=
/mm
Number of slits=1028/mm
Hence, 1028 slits/mm are marked on the grating.
Static friction and normal force? I would Google to double check if I'm right.
