how can i solve this question in a different way than the solution manual?
Two cars with different masses are taking a left turn in a flat road. Which of those cars will experience a bigger (a) centripetal force? (b) centripetal acceleration?
You are on the design team for a new airport. The developer wants to build a hotel as close to the airport as possible. The intensity level of a large jet during takeoff is 140 dB at 50 mfrom the jet.
I need a live person to solve my workout questions?
what fraction of energy will be lost when a moving cart of mass m inelastically collides with a stationary cart of mass 2m?
I just need the answers to the questions no work is needed.
Given Statement: "In free-fall the acceleration is always g and always straight downward regardless of the motion." Three Objections: (a) If I drop a balloon or a feather, it doesn't fall nearly as fa
So I was able to figure out the first question but I'm having trouble with the second question. B/c the calculated vector was composed by adding all the horizontal and vertical components.
Please give me detailed solutions.. step by step... not like some vague solution does not give anything
A 7.5-kg block is sliding down a wall with constant velocity. The coefficient of static friction between the block and the wall is s = 0.70. The coefficient of kinetic friction between the block and

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
