explain if the ice on the polar caps of the earth melts how will it affect the duration of day |
|
Answer» When ice on the polar caps will melt then whole water is spread throughout the earth due to this,moment of inertia will increase and by conservation of angular momentum angular velocity will decrease . Since angular velocity , w= 2π/t , therefore time period will increase,i.e.,duration of day will increase Thanq ?? Nice answer Priya Yes the days would be longer.Since the ice that was at the South Pole is now distributed around the world, there is a change in the distribution of mass. Like an ice skater opening their arms. Since the mass is further from the axis of rotation, the rotation slows; which means the days are longer.this due to increase in moment of inertia |
