Earth completes one revolution round the sun in 365.25 days. What is the angular velocity ? |
|
Answer» Solution :Angle subtended for ONE revolution `=THETA = 360^(@) = 2pi` rad TIME taken `=T = 365.25` days = `365.25 xx 24 xx 60 xx 60` ANGULAR velocity `=omega = (2pi)/T = (2 xx 3.14)/(365.25 xx 24 xx 60 xx 60)` `= 1.9 xx 10^(-7)` rad/s |
