What letter does physical pressure use On the problem of physical drawing
The unit of pressure is PA, i.e. newton per square meter. It is generally expressed by the English letter "P". The unit of pressure is Newton. It is generally expressed by the English letter "F". P = f / S (pressure = pressure △ stressed area)
V = Δ s / Δ T, what does Δ t stand for and what does Δ s stand for
Δ t stands for "time"
Δ s is the "arc length" in Δ t time
