For this setting you should read the meter using the red scale that ends in a black "10" near the letters "A.C." ) Change the Simpson meter to a larger AC voltage scale and determine the RMS voltage across the capacitor, the inductor, and the function...
Example: A satellite blasts off from the surface of the Earth with an initial speed v0 = 2vesc . How fast is the satellite moving when it gets very far from the Earth?
If the ball was kicked at an angle of 45o above the horizontal, what was its initial speed?
The mass of the child is 26.0 kg and that of the boat is 55.0 kg. A ball moving with a speed of 17 m/s strikes an identical ball that is initially at rest. After the collision, the incoming ball has been deviated by 45o from its original direction, and the struck ball moves off at 30o from its...
How does a thin layer of water on the road affect the light you see reflected off the road from your own headlights? How does it affect the light you see reflected from the headlights of an oncoming car?
8. When light (or other electromagnetic radiation) travels across a given region, what is it that oscillates? What is it that is transported? 9. In space sailing, which is a proposed alternative for transport to the planets, a spacecraft carries a very large sail. Sunlight striking the sail...
6. What is the significance of the slope of the plot of ln(V) vs. time for a capacitor discharge circuit?
A. 114C b. 72C c. 64C d. 37C 10. Heat flow occurs between two bodies in thermal contact when they differ in what property? A. mass b. specific heat c. density d. temperature 11. Who demonstrated that when heat is gained or lost by a system during some process, the gain or loss can be accounted...
12. In bombarding atomic nuclei with proton "bullets", why must the protons be accelerated to high energies if they are to make contact with the target nuclei?
45. When food is irradiated with gamma rays from a cobalt-60 source, does the food become radioactive?

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive 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
