Answer:
message flows are modeled with solid arrows
Explanation:
In Business Process Model and Notation (BPMN), message flows are used in the collaboration diagram to show how two or more distinct processes within the model, communicate and collaborate with each other without any form of central control.
Dash lines together with an empty circle are used for the message flow to show where the message comes from and an empty arrow head is used to show where the message would be terminating in the model.
Total cost per week = $3600
The correct option is <u>C.$3,600</u>.
<u>Explanation</u>:
<em><u>Given</u></em>:
Cost for constructing and purchasing the equipment for restaurant = $520,000
Minimum return = 10% of investment
Restaurant is opened = 52 weeks per year
No. of meals = 900 meals/per week
Cost of meal = $5
Expense for material and electricity= $600
Expense for weekly wages = $1000
Fixed cost per week = ([520,000(.10)]/52) + 1000 = 2000
Variable cost = 1000 + 600 = 1600
Total cost = Fixed cost per week + Variable cost
= 2000+1600 = 3600.
Total cost per week = $3600
The property of water that produces water's surface tension is called <u>cohesion</u>, which is the tendency of water molecules to stick together.
More about surface tension:
The force per unit length that must be supplied parallel to the surface in order to balance the net inward pull is known as the surface's "tension."
All nearby molecules in a liquid share the cohesive forces that hold them together. Because they don't have any above-surface neighbours, molecules on the surface exert stronger attractive forces on their closest neighbours below and on the surface.
Due to the cohesive structure of the water molecules, surface tension can be described as the characteristic of a liquid's surface that permits it to resist an external force.
