The atomic number is the same as the mass number but just put amu next to the number
Answer:
Where can I get a can opener? hahaha
Answer:
I'm pretty sure it's going 97
Pressure, P = Force, F/ Surface Area, A
In the current scenario,
Force, F = Weight = mg = 1/1000*9.81 = 9.81*10^-3 N
Surface area, A = πr^2 = π*(0.210/1000)^2 = 1.385*10^-7 m^2
Therefore,
P = F/A = (9.81*10^-3)/(1.385*10^-7) = 70,807.71 N/m^2
