Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa. Physics, 22.06.2019 10:10
Agrindstone in the shape of solid disk with diameter 0.42 m and a mass of 50.0 kg is rotating at 750.0 rev/min. you press an axe against the rim with a normal force of 160 n and the grindstone comes to rest in 7.8 seconds. find the coefficient of kinetic friction between the axe and the grindstone. there is negligible friction in the bearings.

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k
