Having minor homework questions or simply want to make sure your homework answers are correct? Then use our free service to get quick answers to your homework questions in mathematics, physics, programming, economics, chemistry and biology. We already have a database of multiple homework questions and answers you can look through . If you can’t find the solutions to your homework problems, then post your homework questions and find a well-formulated answer from a professional within a very short timeframe.
Please save your time and DO NOT send us your full assignments or not precise, well stated questions in mathematics, physics, programming, economics, chemistry or biology as they will be ignored. In this section we can answer only your short questions of qualitative, primary theoretical nature (for FREE!). Use filters to display the questions to a particular subject or section. By entering your e-mail in the box "Search" you can browse the questions posted exclusively by you. Do not worry if you cannot find your question in the list after it has been submitted; every question is being checked by a moderator and appears in the list only after its approval.

A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 2.75 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 2530 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 3.35 V/m, (b) in the negative z direction and has a magnitude of 3.35 V/m, and (c) in the positive x direction and has a magnitude of 3.35 V/m?
A rock with a mass of 6.0 kg is being whirled in a horizontal circle on the end of a rope 1.6m long. If the speed of the rock is 2.7m/s , what is the magnitude of the centripetal acceleration?
a visitor to a lighthouse wishes to determine the height of the tower. she ties a spool of thread to a small rock to make a simple pendulm, which she hangs down the center of a spiral staircase of the tower. The period of oscillation is 10.8s. The acceleration of gravity is 9.8 m/s. What is the height? Answer in units of m
