The Homework Library (HL) is a database of solved problems.

HL materials are not original and are therefore made available for the sole purpose of studying and learning.
**Misuse of HL materials is strictly forbidden.**

The HL was created for students who need immediate help, and in many cases you can find step-by-step
explanations on how to solve a problem or examples of proper writing, including the use of citations,
references, bibliographies, and formatting.

If you donâ€™t find what you are looking for within our HL database, please reach out to one of our tutors
and schedule a tutoring session.

Explain every solution in detail. A block of mass m1 = 15 kg on a rough 30°-inclined plane is connected to a 5-kg mass (m2) by a string of negligible mass passing over a pulley that is shaped like a disk. The 2-kg pulley has radius 15 cm and rotates about its symmetry axis of rotation. The ...

Please provide the solution in detail. And include every single little step you make in the solution. A 6-kg block (m1), initially at rest on a rough shelf, is connected to a 4-kg block (m2) that hangs by an inextensible string of negligible mass passing over a pulley. The uniform disk-shaped p...

Problem 1: Classical Theory of Conduction Find (a) the current density and (b) the drift velocity if there is a current of 1 mAin Number 14 copper wire (diameter = 0.163 cm). Problem 2: Classical Theory of Conduction How long would it take for an electron to travel a city block (~160 m) if it we...

A glass cell of length D, initially filled with air lies in one arm of a Michelson interferometer that uses light of wavelength λo. Show that filling the cell with a gas with index of refraction ng will result in N fringes being displaced, where N - 4L(ng - 1)/λ0.

Consider this scenario. A car is moving at high speed along a level highway when the driver makes an emergency braking. The wheels become locked (stop rolling), and the resulting skid marks are 32.0 meters long. The coefficient of kinetic friction between tires and road is 0.550, and the accelerati...

Consider the following scenario: a box rests on the horizontal bed of a truck. A a. The coefficient of static friction between the box and the truck bed is 0.19. What maximum distance can the truck travel in 4.0 s, starting from rest and moving forward over level ground with uniform acceleration, w...

Consider the scenario shown here. The mass of the string is negligible, as is the friction in the pulley. The initial position of m1 is 0.23m below the level of the axis of the pulley. The initial position of m2 is 0.68 m below the level of the axis of the pulley. The masses (m1 = 10 kg, m2 = 7.5 kg...

1. Your friend has been given a laser for her birthday. Unfortunately, there wasn't a manual with it so she doesn't know the wavelength that it emits. You perform a double slit experiment, with slits separated by 0.36 mm. You find that the two n=2 bright fringes are 5.5 mm apart on a screen 1.6 ...

Use the field and subject filters to browse through Homework Library solutions that pertain to your areas of interest. We are adding new content to the library on a daily basis, so check back from time to time. If you'd like us to post solutions in a subject we don't yet have content for, let us know - we'd like to hear from you!

The solutions will include information such as the original question and sometimes a preview of the solution itself. When you are ready to purchase a solution just click on it and it will be yours.

There is no time limit. Once you purchase a solution you'll have access to it for as long as your registration on the site remains valid. If you can log into your account, you can view any purchased solutions.
