Answer 2

Explanation:

• It is true that when tall buildings are constructed on earth, the duration of day-night increases.
• But, the change is very minute and cannot be felt by humans.
• This is because, when tall buildings are constructed, the moment of inertia of earth about its axis of rotation slightly rises and the angular velocity of the earth around its orbit is reduced to keep the angular momentum constant.  
• This means that the earth rotates slower than the usual to complete a day and night. This phenomenon takes place to conserve the angular momentum.
