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)

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

The short distance from the objective lens to the object causes problems at high magnification. which of the following is the most serious? a. cleaning the object surface b. positioning the object c. reflection from the object surface. d. illumination of the object
