An engineering team has come to the stage in the engineering design process in which it is iterating to improve the solution. What is one thing the
team might be doing?
A. Defining the problem so that the team can identify the criteria and
constraints of the chosen solution
B. Improving its design based on the results from tests on the
prototype
O C. Analyzing the prototype so that the team can brainstorm multiple
solutions to the design problem
D. Defining the criteria and constraints so that the team can design a
model to test its chosen solution

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
