Answer:
<u><em>To answer this question we assumed that the area units and the thickness units are given in inches.</em></u>
The number of atoms of lead required is 1.73x10²³.
Explanation:
To find the number of atoms of lead we need to find first the volume of the plate:
![V = A*t](https://tex.z-dn.net/?f=%20V%20%3D%20A%2At%20)
<u>Where</u>:
A: is the surface area = 160
t: is the thickness = 0.002
<u><em>Assuming that the units given above are in inches we proceed to calculate the volume: </em></u>
Now, using the density we can find the mass:
![m = d*V = 11.36 g/cm^{3}*5.24 cm^{3} = 59.5 g](https://tex.z-dn.net/?f=%20m%20%3D%20d%2AV%20%3D%2011.36%20g%2Fcm%5E%7B3%7D%2A5.24%20cm%5E%7B3%7D%20%3D%2059.5%20g%20)
Finally, with the Avogadros number (
) and with the atomic mass (A) we can find the number of atoms (N):
Hence, the number of atoms of lead required is 1.73x10²³.
I hope it helps you!

Answer:
Explanation:
The VC-T engine (for "variable compression, turbocharged") can adjust its compression ratio between 8:1 and 14:1 on the fly, offering high-compression efficiency under light loads and the low compression needed for turbocharged power under hard acceleration.
