Q37,If earth contracts to half of its radius, what would be the length ofthe day? |
|
Answer» conservation of angular momentumIw =constant for solid2/5 mR²w= constant wR²= constant 2πfR²= constant R²/T = constant so, T is directly proportional to square of radius Thus if radius is decreased to half then,T'= T/4which is 24/4time period will be 6 hours. |
