The ammeter in the gure reads 1.6 A. a) Find I1 b) find I3 c) Find epsilon.
Consider the circuit in the gure. a) Find the current in the 2 resistor b) Find the current in the 7 resistor. c) Find the current in the 6 resistor.
Assume: The battery is ideal (it has no internal resistance) and connecting wires have no resistance. Unlike most real bulbs, the resistance of the bulb in the questions below does not change as th
Unlike most real bulbs, the resistance of the bulb in the questions below does not change as the current through it changes. A capacitor, a bulb, and a switch are in the circuit as shown below in
Weight, Normal: You and a few friends have decided to open a small business called Wee Deliver. The business will guarantee to deliver any box between 5 lbs. and 500 lbs. to any location in the Twin
A light bulb is wired in series with a 133- resistor, and they are connected across a 120-V source. The power delivered to the light bulb is 24.3 W. What are the two possible resistances of the light
A particle has a charge of -3.6 C and a speed of 160 m/s when it enters an area of space where there is a constant magnetic field with a strength of 0.048 T. The particle enters in different direct

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
