Two machines are capable of doing the same work. Should they have the same power?

Text Solution

AI Generated Solution

To determine whether two machines capable of doing the same work should have the same power, we can analyze the relationship between work, power, and time. ### Step-by-Step Solution: 1. **Understanding Work and Power**: - Work (W) is defined as the energy transferred when a force is applied over a distance. - Power (P) is defined as the rate at which work is done. It can be expressed mathematically as: \[ ...
