Write a function gcdwith coefficients which, given positive numbers nand m, returns a three-tuple (g, s,t) were g is the greatest common divisor of mand n, and s and t are numbers such that s*m + t*n = g.(use the euclidean algorithm to do this.)the typefor this function is given bygcd with coefficients: : (integral a) => a -> a -> (a, a,a)

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
