Physics Problem Solver

Physics Problems play a special role in physics and it makes the physics just like an exciting game. But some students don't realize that. So, while dealing with physics, many of them have a feeling why do problems come? Understanding the physics theory and formula is enough why do we need problems? They even feel panic when problems part come.  So, there is an Excellent Solution for this problem where you can get the solved problems in an systematic way in the form of steps that will make you analyze the problems.

                                                      

You may have come across many problems in physics where you get stuck and don't feel like moving further unless you solve it and if you are not able to solve it, then you tend to think that physics is very tough and end up lacking interest in physics. For this we are providing equipment of interest for physics problems through our website which will solve all your problems through our Online Tutors. These tutors have mastery on the subject and can help the students solve their problems.

Physics Problems and Solutions

Physics problem solvers are available online to help you understand the subject. They help you solve both simple and complex physics problems and score well in the subject.
Besides problem solvers, a lot of online sites and resources are also available to make physics simple.
With step-by-step explanations and solved and unsolved practice problems, they provide students with plenty of opportunities to hone their physics problem solving skills.
Practice and thorough understanding of concepts are the key to getting great grades in physics. This is where the physics equation solver makes things easy.

It is a great online tool which any student can use to learn physics.

We are solving the problems with the following steps which will help the student analyze the problem:

  • Description
  • Explanation
  • Formula Display
  • Diagram ID

Given below are some solved sample problems:


Solved Examples

Question 1: A and B are two engines. A operates with reservoir temperatures 1000K and 500K while B operates with reservoir temperatures 500K and 300K.
(i) Calculate the efficiency of both engines A and B
(ii) Which Engine is more efficient?
Solution:
(i) For Engine A, T1 = 1000K,
                              T2 = 500K
$\eta$ = {1- $\frac{T_{2}}{T_{1}}$}
            = {1- $\frac{500}{1000}$}
            = 1 - 0.5
            = 0.5
$\therefore$ The efficiency of engine A is 50%
(ii) For engine B, T1 = 500K
                               T2 = 400K
$\eta$ = {1- $\frac{T_{2}}{T_{1}}$}
            = {1- $\frac{400}{500}$}
            = 1 - 0.8
            = 0.2
 The efficiency of engine B is 20%
$\therefore$ engine A is more efficient compared to engine B.
 

Question 2: An electric heater has resistance of 20 $\Omega$ and draws a current of 10 Amperes. What Voltage should be set for it?
Solution:
Given I = 10 A,
          R = 20 $\Omega$
According to Ohms law, V = IR
where V = Voltage,
            I = Current,
           R = Resistance.
$\therefore$ V = 10 $\times$ 20
     = 200V.
