3. In this problem we will numerically explore our model for stellar pulsation from Lecture(April 7), looking at the equation of motion for a spherical shell at the surface of astar:md2Rdt2= mdvdt = G M mR2+ 4 R2Pwhere M is the mass of the star, m is the mass of the shell, v is the outward...

CP and T violations problem
suppose L1 has a focal length of -5 cm. This is in direct contact with a second lens named L2. If an object is placed 5 cm from the lens combination, the resulting magnification is seen to be M=-10. Find the focal length of the second lens in the combination.
A crate whose mass is 360kg rests on the bed of a truck that is moving at a speed of v0 of 105 km/h. The driver applies the brakes and slows down to a speed v of 62 km/h in 17 s. What force (assumed constant) acts on the crate during this time?
Find the maximum possible number of photons emitted by a hydrogen electron located at the energy level n = 3?
a heating element is rated at 12v AC peak. it is used to heat the water in a small container. when operating the element has a resistance of 5 ohms. how much power does it use?
A piece of gold with a mass of 5.50 kg and density of 19300 kg/m 3 is suspended from a string and then totally immersed in a beaker of water. Using density of water is 1000 kg/m 3 a) Determine the volume of the piece of gold. b) Determine buoyant force on the gold when it is submersed.
See HW 12.pdf Need to solve the attached two problems. Please show all work.
Two parallel conducting plates are separated by the distance d, and the potential difference between the plates is maintained at the value (delta) Phi . A slab of dielectric that has dielectric constant k and a uniform thickness d is inserted snugly between the plates. Because it could be...

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
