Fill-in-the-blank: A _____________ of fundamental rotations about the unit vectors cause composite rotations.

A vector quantity possed by a body by virtue of its rotation is called angular momentum.a.Trueb.False

Match the correct statement.The composition of two reflections over parallel lines separated by x units is equivalent to a translation of 2x units.Answer 1 Question 7A composition of two reflections over lines that intersect at x° is the same as a rotation of 2x°. The center of rotation is the point of intersection of the two lines of reflection.Answer 2 Question 7If you combine two reflections along each axis, the final image is a 180° rotation around the origin of the original.Answer 3 Question 7

one side of the composition might contain a dominant element, which could be balanced by a couple or more lesser focal points on the other side.radialsymmetricalasymmetrical
