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.

1.4 Limitations to Spherical Lenses In class we mentioned that a sphere is a good - but not perfect approximation of an ideal lens. a) Suppose we make a single refractive surface with index of refraction n = 1.6 (immersed in air, n a 1 and a radius of curvature of 50 cm. What will the back focal ...

Attwood's machine A uniform circular pulley of mass 2m can rotate treely about Its axis 12.2 of symmetry which is fixed in a horizontal position. Two masses m, 3m are connected by light inextensible string which passes over the pulley without slipping. The whole system undergoes a planar motion...

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.
