In the figure a 19 V battery is connected across capacitors of capacitances C 1 = C 6 = 4.0 F and C 3 = C 5 = 1.5 C 2 = 1.5 C 4 = 6.0 F. What are (a) the equivalent capacitance C eq of the capacitor
An electron and a proton are fixed at a separation distance of 901 nm. Find the magnitude and direction of the electric field at their midpoint. Magnitude:
Two charges are located in the x y plane. If q1 = -4.70 nC and is located at x = 0.00 m, y = 0.960 m and the second charge has magnitude of q2 = 4.20 nC and is located at x = 1.40 m, y = 0.450 m, calc
A paper-filled capacitor is charged to a potential difference of 2.1 V and then disconnected from the charging circuit. The dielectric constant of the paper is 3.7. Keeping the plates insulated, the p
A tennis ball on Mars, where the acceleration due to gravity is 0.379 of a g and air resistance is negligible, is hit directly upward and returns to the same level 9.00 s later. Part A How high above

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
