If all people in earth took elevators to the tops of high buildings in their communities, estimate the effect of this on the length of the day. explain
Homework Answers
here,
as the moment of inertia of earth will increase
moment of inertia = m * r^2
when the distance from the center of earth increase
the moment of inertia of earth will increase
as the angular momentum is conserved
the angular speed of earth will decrease
and time period = 2pi/angular speed
the angular speed of earth will decrease
therefore , the timeperiod increases
and the length of day also increases

The people of Malaysia belong to three communities: the local people called Malays, immigrants from South India called Tamils, and immigrants from China. During the early 20th century, the Malays lived mainly in coastal villages, the Tamils worked on rubber estates, and the Chinese worked in tin mines. In general, the people were very poor and they consumed a limited variety of foods.[1] Rice was the staple diet of all three communities and therefore the key source of caloric and...

Many people believe that a high interest rate is bad for the economy. Of course, all else equal, a higher interest rate means grater borrowing costs for firms. But a high interest rate is also helpful to some people in the economy. What group of people benefits from a higher interest rate? Explain how they benefit. A high interest rate can also indicate that something positive is happening in the economy. Describe how positive factors can lead to an increase...
