A car is parked 24.0 m directly south of a railroad crossing. A train is approaching the crossing from the west, heading directly east at a speed of 56.0 m/s. The train sounds a short blast of its 275
A thin 5.2-m metal rod sustanins a longitudinal standing wave with vibration antinodes at each end of the rod. There are no other antinodes. The density and Young's modulus of this metal are, respecti
Two wires, each of length 1.3 m, are stretched between two fixed supports. On wire A there is a second-harmonic standing wave whose frequency is 711 Hz. However, the same frequency of 711 Hz is the th
Refer to Interactive Solution 17.45 to review a method by which this problem can be solved. The fundamental frequencies of two air columns are the same. Column A is open at both ends, while column B i
Sound (speed = 343 m/s) exits a diffraction horn loudspeaker through a rectangular opening like a small doorway. A person is sitting at an angle off to the side of a diffraction horn that has a widt
Need help with lab experiment.
Need help completing the tables and answering the questions from this experiment. The protocol and document is attached.
In Concept Simulation 17.1 you can explore how two pulses, traveling in opposite directions, combine to form a resultant pulse. Two pulses are traveling toward each other, each having a speed of 1 cm/
Please answer these questions Thank you! I need them ASAP!!LIKE TODAY OR TOMORROW MORNING WOULD BE AWESOME!! 1.How many neutrons are in Hg if the mass number is 201? 2.The mass number tells the tota
Hi i ONLY NEED help with question 19 and 20 please!!!Only the diving question and square question which are 19 and 20! The rest i already have answered!!

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
