<span>Electron because it is incredibly small. like 1840 times smaller than the proton. and it travels around the proton. The nucleus is made of proton and neutron and electron travels around it.</span>
The SI unit for the amount or quantity of small particles in a sample is referred to as the mole.
This tells how much in terms of atoms or molecules are present for a particular mass.
In the sliding filament model of muscle contraction, the myofilaments slide over each other, resulting in the overlapping of actin and <span>myosin. Hope this helps. Have a nice day. Feel free to ask more questions. Thank you.</span>
This is a short answer but because they have the same amount of protons and electrons but different amount of neutron
Since we have the mass of the iron ingot we can get its volume by dividing the mass (4.578) by the density of iron (7874 kgm^-3) and we get that the volume is 5.8140716x10^-4 m^3. now we convert the volume from m^3 to cm^3(1m^3=1000000cm^3) and so by multiplying 5.8140716x10^-4 by <span>1000000 we get:581.4cm^3 (1 decimal place).
the volume for any cuboid is V=l x w x s we have the volume, the length and the width, so we plug in the values and solve for s
</span>

the answer is rounded to three significant figures
hope i helped
