1. Describe the interaction between the vector transformation and the substitution of coordinate points. 2. How does the coordinate system fit into the criteria of geometry? 3.justify; Cartesian coordinates can be linked to spherical and cylinder coordinates. Indicate whether the assertion is accurate or not. 4. Find out what makes circular waveguides superior to rectangular waveguides. 5. Determine the flow direction of a cylinder containing charges. The pressure in a piston cylinder is a variable of?explain 7.justify; Waveguides use a round and hollow design. By considering the referral in terms of the cylinder-shaped coordinate system, you can get rid of the requirement for the waveguide to be spherical. A spherical system, for instance, is
