The typical Canadian worker is able to produce 100 board feet (a unit of measure) of lumber or 1000 light bulbs per year. The wo
1 answer:
Answer:
Explanation:
In the Canadian country, it is possible that the country is able to produce either 100 units of lumber or 1000 lightbulbs. Then, 100 lumber is equal to 1000 bulbs in the home, and hence, one lumber is equivalent to 10 bulbs. Therefore, the opportunity cost of lumber in the home is ten bulbs.
Thus, the country's production possibilities frontier PPF is a linear combination of 100 lumber and 1000 bulbs. The graphical diagram of the production possibilities frontier PPF can be seen in the image below.

Answer:
The mass flow rate of cooling water required to cool the refrigerant is .
Explanation:
A condenser is a heat exchanger used to cool working fluid (Refrigerant 134a) at the expense of cooling fluid (water), which works usually at steady state. Let suppose that there is no heat interactions between condenser and surroundings.The condenser is modelled after the First Law of Thermodynamics, which states:
The mass flow rate of the cooling water is now cleared:
Given that ,
,
and
, the mass flow of the cooling water is:
The mass flow rate of cooling water required to cool the refrigerant is .
Answer:
4.83m/
Explanation:
For a particle moving in a circular path the resultant acceleration at any point is the vector sum of radial and the tangential acceleration
Radial acceleration is given by r
Applying values we get X0.3m
Thus
At time = 2seconds
The tangential acceleration is given by
Thus the resultant acceleration is given by
