How is the coronavirus pandemic affecting the labour market and education plans for Canadian University students? (Students may have lost their ability to support themselves through work or with help from family, there may be foreign students who face travel restrictions, etc., some may be graduating into a market with poor employment prospects while carrying large student loans, etc. List all the possible problem scenarios that you can think of.)

What is convection cooling? How can you construct a building so that convection cooling occurs?

What are thermal bridges? Give an example of some ways to eliminate them when you are building?

What is the intention of the Innovation and Design Credits? What are the responsibilities of the LEED Accredited Professional on a project?

Bridges Not Walls uses a metaphor of breathing (inhaling/exhaling) to explore the process of interpersonal communication. Use stereotyping to define the concept and discuss why it is important for interpersonal communication to be effective, what skills are necessary, and implications when these skills are lacking. Support assertions with references to Stewart and his co-authors.

I would like to power and drive a vehicle using:

2 x 6V geared mini DC motors
1 x 5V Color recognition sensor
1 x Arduino Nano

I this possible? If so please explain how and provide a detailed schematic and list of parts needed. How do I supply 6 V to each motor, if the Arduino Nano only puts out 5 V?

Thanks

Q27. Data 105, 91, 52, 86, 100, 96, 98, 109, 96, 95 , 57

Suppose we have assigned grades for the 11 students in our data:Grade A for students who scored ≥ 90; B for students who scored ≥ 80 and < 90; C for students who scored ≥ 70 and < 80; D for students who scored ≥ 60 and < 70; F for students who scored < 60.

Following the above grade scheme, we observe that we have 7 students who received grade A, 1 student received grade B, 0 students received grade C, 0 students received grade D and 1 student received grade F. Using this, please answer the following questions:
