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:
The correct answer is (d)
Explanation:
Better quality can help to reduce many costs such as customer’s dissatisfaction cost, inspection cost and warrant and service cost. When customers don't like the quality of the product they are likely to buy the same product from somewhere else that is the dissatisfaction cost. Still, maintenance cost is likely to incur no matter how good the quality is. Maintenance cost helps to keep the product clean and fresh for long-term use.
Answer:
WACC is 9%
Explanation:
WACC is the average cost of capital of the firm based on the weightage of the debt and weightage of the equity multiplied to their respective costs.
According to WACC formula
WACC = ( Cost of equity x Weightage of equity ) + ( Cost of debt ( 1- t) x Weightage of debt ) + ( Cost of Preferred equity x Weightage of Preferred equity )
As per given data
Market Values
Equity = $7 billion,
Preferred stock = $2 billion
Debt = $13 billion
Cost
Equity
Capital asset pricing model measure the expected return on an asset or investment. it is considered as the cost of common stock.
Formula for CAPM
Cost of Equity = Risk free rate + beta ( market return - risk free rate )
Cost of Equity = Rf + β ( Mrp )
Cost of Equity = 3% + 1.6 ( 8% ) = 15.8%
Preferred stock = $2 / $26 = 0.077 = 7.7%
Debt = 8%
Placing values in the formula
WACC = ( 15.8% x $7 billion / $22 billion ) + ( 8% ( 1- 0.3) x $13 billion / $22 billion ) + ( 7.7% x $2 billion / $22 billion )
WACC = 5.03% + 3.31% + 0.7% = 9.04%
Answer:
D. define the project
Explanation:
The project is defined in the initiation phase.
The Project Initiation Phase is the 1st phase in the Project Management Life Cycle, as it involves starting up a new project. You can start a new project by defining its objectives, scope, purpose and deliverables to be produced.
