a 3.000 kg ball is pitched with a kinetic energy of 20.00 Joules. Then the momentum of the ball is:
In a collision between an electron and a hydrogen atom, it is useful to select both objects as the system because: 1) The forces the objects exert on each other are internal to the system and don't

1. The planet Neptune is the most distant planet that we have studied so far. The semi-major axis of its orbit is approximately 30 AU, that is, it is 30 times farther from the Sun than the Earth.
Please explain number 8 from the attached file.
Please explain number 10 from the attached file.

Tips for Asking Questions
- Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
- 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.
1. Can you show me step by step how to solve this problem?:
- 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?
2. I do not understand this Ideal Gas Law and Kinetic Theory question. Can you help me set it up?
- A spherical balloon is made from a material whose mass is 3.00-kg. The thickness of the material is negligible compared to the 1.5-m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305-degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19-kg/m^3. Find the absolute pressure of the helium gas
