From the subject of economics, specifically macroeconomics, it says that the statement above is false. <span>Business cycles, not business fluctuations, are systematic increases and decreases in real GDP. Business fluctuations are called unsystematic changes. </span>
The synchronous speed (rpm) equals 60 times the frequency divided by the number of pole pairs. For 50Hz, a two-pole motor will have a synchronous speed of 3000 rpm, a four-pole motor of 1500 rpm.
The actual speed is a few percent lower due to the slip of the asynchronous motor.
The slip increases with the torque, typical values are 5–10%. The rated speed for a four-pole motor at 50Hz will thus be something like 1360 rpm. At no-load, the slip is very small.
Answer:
Doing the right task is known in management as performance.
Explanation:
Management ensures that the right tasks are performed by coordinating the various activities that help it to achieve goals. It also plans the right tasks to be carried out in order to achieve set goals and objectives. In doing all these, it also considers the cost and benefit to be incurred and derived respectively from executing its responsibilities. Management is always interested in minimizing costs while maximizing benefits. Management is also concerned with efficiency, by which it minimizes the wastage of resources (such as time, money, and efforts) and ensures optimum utilization of all its resources.
Answer:
Accept Project A and reject Project B
Explanation:
See the images to get the answer.
Decision: Required rate of return = 16% = Cost of capital.
If Internal rate of return (IRR) > the cost of capital = Accept the project.
If Internal rate of return (IRR) < the cost of capital = Reject the project.
From the basis of the formula, we can accept the project A because the IRR of Project A (19%) is higher than the cost of capital (16%). On the other hand, we can reject the project B because the IRR of Project B (14%) is smaller than the cost of capital (14%).
