           Hello everyone, welcome back to my blog. This is just a bonus post, so I'll be solving only one question today in physics. That being said, let's get back to it. Question 1.  Two mass 6kg and 4kg hung on a frictionless pulley with an inextensible string:  a)  find the acceleration b)  tension of the string                                          (g=10m/s²)     Solution         To solve this question, you should at least have a basic knowledge or an idea on the  Forces and Pulley system . That would help you understand this solution. From the question, we were given two masses 6kg and 4kg respectively. Suppose the small m represents the 4kg mass and the M represents the 6kg mass, the whole system would move to the right as seen in the picture below. Force Diagram           The system doesn't have x-components (horizontal forces) because it's only moving in the y-direction (vertical forces). So, all we need to sum up the forces in the y-component for each

            Welcome back to my blog. I know it's been a while since I posted anything on my blog. Today, I'll be posting some questions and solutions about some familiar chemistry concepts. I took most of these questions from the  *P.UTME CHAMPIONS GROUP; although, I edited somethings in the questions.  These questions are multiple-choice questions, so we'll be able to do some guesses and eliminations to derive our answers. That's because some options are meant to divert your focus from the real question  for you to get the question wrong. I call them distractions . I'll also be explaining why an option is right or wrong in my solutions below. Note that the correct answers will be boldened alongside its option (letter).         Now, let's take a look at these questions and see their respective solutions:   1. In principles that govern electron filing into orbitals, which of the following rules states that in the building up of atoms, electrons enter into orbit
