Given the following bdd fragment:

A user provides login credentials to the User Interface, and the Controller passes this information to the User Database The User Database in turn validates the user name and password (typed by PW In the <flow Specification>) and responds with a Boolean value indicating whether the login was successful. The Controller provides the password to the Key Generator if login was successful.

Given a system for keeping birds away from airports One component, described by the following diagram directs audio signals at birds that approach a runway, its parts, as part properties, are typed by blocks.

A systems engineer has identified some blacks that type the pan properties, but as the design becomes more specific, the engineer discovers that these blocks exist in multiple variants.
What modeling choice does the engineer face at this point?

NO.66 Choose the correct answer.
A system engineer specializing in rigid body dynamics wants to model the laws of motion (LOM) so that they may be reused to analyze different types of systems. The LOM consist of the mathematical relations R1 and R2. shown here.
(R1)s=ut + (1/2)at2
(R2) v = u + at
How should the system engineer represent and relate LOM. R1, and R2 in SysML?
