The opportunity cost would then be not having the orange.
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: (D) Product line
Explanation:
The product line is basically refers to the group of the product in which the similar company or organization selling their products and brands.
In the product line concept, the companies are basically expanding their business by selling their existing products according to the customer requirement and the usability. It is also known as marketing and the product strategy for increase their productivity.
