discovered planet has twice the mass of the Earth, but the acceleration due to gravity on the new planet's surface is exactly the same as the acceleration due to gravity on the Earth's surface. The ra

a point source of light is 160 cm below the surface of a body of water. Find the diameter of the circle at the surface through which light emerges from water?

Two steel wires of the same length, one with radius r and the other with radius 2r, are connected together, end to end, and tied to a wall. An applied force stretches the combination by d = 1.8 mm. Ho

The Westin Stamford Hotel in Detroit is 228m tall. Suppose a piece of ice, which initially has a temperature of 0.0 degree C falls from the hotel roof and crashes to the ground. Assuming that 50.0 per

You are given a sealed box with two electrical terminals. The box contains a 5.00 ohm resistor in series with either an inductor or a capacitor. When you attach an ac generator with an rms voltage of

Consider a +2.0x10^6C charge on the yaxis at y=5m and a 4.0x10^6C charge on the xaxis at x=4m. What is the potential at the origin relative to V=0 at infinity is, in volts?

A 40.5 mA current is carried by a uniformly wound aircore solenoid with 467 turns as shown in the figure below. The permeability of free space is 1.25664 10 6 N/A2. Compute the magnetic field

A metal tank with volume 3.10 L will burst if the pressure of the gas it contains exceeds 100 atm. (a) If 11.0 mol of an ideal gas is put into the tank at a temperature of 23.00C, to what temperature

Part 1) Through what potential difference would an electron have to be accelerated from rest to give it a de Broglie wavelength of 1.2 10^ 10 m? The mass of an electron is 9.109 10^ 31 kg and

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.
Sample Questions
 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?
1. Can you show me step by step how to solve this problem?:
 A spherical balloon is made from a material whose mass is 3.00kg. The thickness of the material is negligible compared to the 1.5m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19kg/m^3. Find the absolute pressure of the helium gas
