Kinetic Energy= 0.5 times velocity squared times mass
So KE= 0.5times 150 times 40 squared
(Use a calculator)
And don't forget units
I very much Disagree. The esophagus runs from your mouth to your stomach.
It would be count ice layers
Just remember how many electrons can each sublevel hold.
S=2
P=6
D=10
Since we have 10 for atomic number, we can assume we have 10 electrons
1S2
2S2
2P6
The rest have zero because we already have 10 (2+2+6=10)
