Write a C program (partcopy) that allows a user to extract some part of an existing file (fileSource) and copy it to a new file fileTarget. The user can specify the number of bytes (num1) from the beginning of filesource, how many bytes (num2) that will be extracted from it, and the new fileTarget name. g

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
