Final answer:
The question cannot be accurately answered with the provided information; specific details about the pump's required performance are needed, and without these details the minimum output rating in watts for the pump motor cannot be determined.
Step-by-step explanation:
The question asks to determine the minimum output rating in watts that a pump motor must have. To answer this question accurately, it is necessary to know the specific details about the pump's required performance, such as lifting weight, height, and efficiency. Unfortunately, the provided information does not contain these details, thus making it impossible to determine the exact output rating required for the pump motor. Additionally, the hint provided suggests that solving for power in watts and rounding to a nice number may be part of a problem-solving strategy; however, without additional context, this hint cannot be directly applied to ascertain the minimum output rating for the pump motor.
When dealing with power requirements, power consumption, energy efficiency, and electrical calculations are important considerations. To arrive at a solution, the relationship between power (in watts), energy (in joules or kilowatt-hours), and time must be understood, and the relevant calculations applied. For educational purposes, understanding the principles of physics surrounding energy transfer and power in electrical applications is critical.
