C. It Is a special kind of activity node that can be used to control the flow of tokens into an activity.

D. It Is an activity node that allows a modeler to specify the use of mathematical operators such as plus minus, multiply, or divide.

The essentials of a laptop battery capacity model are shown In the following diagrams (where the value types W, h and Wh stand for watl, hour, and watt-hour respectively). Assume that the instance values shown are inputs, and that nothing relevant has been omitted.

The designer needs to determine what the energy_capacity of battery 1 should be to enable a laptop usage_time_capacity time of 8 hours. Which combination of the options listed in the text box in the figure will achieve this Intent with minimal changes (including minimal new aspects)?

A. O1.1 and O2 1

B. O1.1 and O2 2

C. O1 1 and O2 3

D. O1.2 and O2.1

E. O1 7 and O2.2

F. O1.2 and O2.3

G. O1 3 and O2 3

Which SysML construct is used in an activity diagram to associate an actor of a use case with the actions that actor performs?

A. an activity partition enclosing the actions the actor performs

B. an action allocation of the actor to the actions that actor performs

C. an association Between the actor and the actions that actor performs

D. an object node to represent the actor and object flows tying that actor to the actions it performs

What is one key advantage of using SysML parametrics versus traditional derived properties?

A. A derived property requires an additional constraint expression, whereas SysML parametrics does not.

B. OCL-based constraint expressions can be used with SysML parametrics but not with derived properties

C. it takes many more steps to specify derived properties in the typical tool compared to specifying constraint blocks.

D. SysML parametrics supports non causal expressions, whereas a derived property involves an expression with a fixed output direction

B. (partial, exclusive)

C. {Incomplete, xor)

D. (incomplete disjoint)

E. {subset, disjoint}
