A line in a drawing is 3 inches long, when measured.  If the drawing scale is 20:1, how long is that edge (the line) in the actual object

(b) A ship is moving relative to the water and you are given the following velocities: Magnitude Direction (degrees) (kn/hour) Velocity Absolute water velocity (tide) Ship's velocity relative to water 8 120 20 90 The directions are measured clockwise from due north (i.e. due east is 90°). What is the ship's absolute velocity (magnitude and direction)?

The volume of a gas is changed along the curved line between A and B in the drawing. Do not assume that the curved line is an isotherm or that the gas is ideal. What is the work done for the process? Number i Units Pressure 2.0 x 104 Pa 0 2.0 x 10-3 m3 Volume

prepare and submit an oblique drawing based on the 2D Multiview object drawing.

The figure shows a wooden model to reproduce a metal piece ofaluminum through the sand casting process.a) How much mass (g or kg) of aluminum do you need to melt?b) How much energy Q (Joules) is required? Assume an initial temperature of 50 ° C and a100% thermal efficiency.c) What dimensions will the final metal piece have? all is in cm
