Final answer:
To find out how many degrees an electric motor rotates in one second from 3,000 rpm, we convert revolutions per minute to revolutions per second, then multiply by 360 degrees to get 18,000 degrees per second.
Explanation:
To calculate the number of degrees an electric motor rotates in one second, first we need to understand the relationship between revolutions per minute (rpm) and degrees. There are 360 degrees in one revolution, so if a motor makes 3,000 revolutions per minute, we use the following steps to find the degrees turned per second:
- First, convert revolutions per minute to revolutions per second by dividing by 60 (since there are 60 seconds in a minute). 3,000 rpm ÷ 60 seconds = 50 revolutions per second.
- Next, convert revolutions per second to degrees per second by multiplying by 360 degrees (since there is one revolution per 360 degrees). 50 revolutions per second × 360 degrees = 18,000 degrees per second.
Therefore, the motor rotates 18,000 degrees in one second.
