Which has less angular speed, hour hand of clock or the angular speed of earth on its own axis? |
|
Answer» Solution :Angular SPEED of earth is LESS For earth angular speed `omega_(e)=(2pi)/(24xx3600)" rad/s"` `omega_(h)=(2pi)/(12xx3600)" rad/s"` `THEREFORE (omega_(e))/(omega_(h))=(1)/(2)` `therefore 2omega_(e)=omega_(h)` `therefore omega_(e)ltomega_(h)` |
