2. Calculate the magnitude of the electric field at one corner of a square 1.1 m on a side if the other three corners are occupied by 3.05x10-6 C charges. in N/C
1. A point charge of +5Q is placed at the center of a square. When a second point charge of -Q is placed at one of the square's corners, it is observed that an electrostatic force of 3 N acts on the p
1. A proton moving to the right at 6.2 105 ms-1 enters a region where there is an electric field of 62 kNC-1 directed to the left. Describe qualitatively the motion of the proton in this filed. What
2. Two spherical point charges each carrying a charge of 40 C are attached to the two ends of a spring of length 20 cm. If its spring constant is 120 Nm-1, what is the length of the spring when the c
3. Two points A and B lie 20 cm apart on a line extending radially from a point charge Q. If the potential at A is 150 V and the potential at B is 120 V, find the charge Q and the distance of point A
An electron is initially at rest just outside a large copper surface that has a charge density of 1.20 10-6 C/m2. How far has the electron moved in 1.01 10-9 s if the field is uniform over this regi
a worker at the top of a 629-m-tall television transmitting tower on north dakota accidentally drops a heavy tool. If air resistance is negligible, how fast is the tool going just before it hits the g
I'm having difficulty answering the following question: The electric eld at a location C points north and has a magnitude of 6 10^5 N/C. Where should you place a proton and an electron (charge |q|
1)A rock is thrown horizontally from the top of a building with an initial speed of v = 11.1 m/s. If it lands d = 43.5 meters from the bottom, how high is the building? 2)Salmon often jump upstream t

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
