 Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price speeds up the process by avoiding any unnecessary price negotiations.
Sample Questions
 The Earth’s rate of rotation is constantly decreasing, causing the day to increase in duration. In the year 2000 the Earth takes about 0.548 s longer to complete 365 revolutions than it did in the year 1900.
 (a) What is the average angular acceleration of the Earth?
 (b) If this average acceleration remains constant, in what year will the Earths rotation come to rest?
1. Can you show me step by step how to solve this problem?:
 A spherical balloon is made from a material whose mass is 3.00kg. The thickness of the material is negligible compared to the 1.5m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19kg/m^3. Find the absolute pressure of the helium gas
