The speed of the center of the earth as it orbits the sun is 107257 kmph and the absolute angular velocity of the earth about its north-south spin axis is 7.292(10-5) rad/s. Use the value for the radius of the earth as 6371 km and determine the velocities of points A, B, C, and D, all of which are on the equator. The inclination of the axis of the earth is neglected.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
