Parallelogram and Triangle law of forces    If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a parallelogram, then their resultant isrepresented in magnitude and direction by the diagonal passing through the point. Parallelogram law of forces If two forces acting at a point are represented in magnitude and direction by the two adjacent sides of a parallelogram, then their resultant isrepresented in magnitude and direction by the diagonal passing through the point. Explanation Consider two forces Vector P and Vector Q acting at a point O inclined at an angle θ as shown in Fig.. The forces Vector P and Vector Q are represented in magnitude and direction by the sides OA and OB of a parallelogram OACB as shown in Fig. The resultant Vector R of the forces Vector P and Vector Q is the diagonal OC of the parall

Physicist Learn interesting facts and information about a range of science jobs and careers. What is a physicist? What do they do as part of their job? Read our job description facts and information to find out the answers to these questions and more while learning all about physics careers.   Scientists who research in physics are called physicists. Physics is an area of science that covers the study of matter, energy and forces. Physicists study everything from tiny atomic particles to the entire Universe as a whole. Physicists observe natural phenomena and use mathematics to develop theories which help explain why they occur. Some physicists study theory while others appl

Science Electric eels deliver taser-like shocks In a painful experiment, a US researcher found out just how strong the jolts delivered by the fish are. He had previously found that electric eels have a special technique that makes their shocks extra-efficient. Now that's dedication to science: researcher Kenneth Catania tested how strong the jolts are that electic eels use to shock their victims – on himself. Catania, a biology professor at Vanderbilt University in Nashville, in the US state of Tennessee, wanted to understand the dynamics of the circuit created in an electric eel attack. For this, he developed an apparatus that can measure the strength of the electric current through a human arm that gets touched by an electric eel. The experience, Catania wrote in the journal Current Biology, is quite painful. In his study published on Thursday, the researcher reports that electricity peaked at 40 to 50 milliamps. That's stronger than the jo

Make Lemonade Fizzy Drink There's a lot of people out there that like drinking fizzy drinks, so why not do a fun science experiment that leaves you with your own lemon soda to drink afterwards! A bit of lemon here and a bit of baking soda there and before you know it you'll be an expert at making your own fizzy drinks. Make your own lemonade softdrink with this fun experiment for kids.   Sponsored Links What you'll need: Lemon Drinking glass Water 1 teaspoon of baking soda Some sugar to make it sweet Instructions: Squeeze as much of the juice from the lemon as you can into the glass. Pour in an equal amount of water as lemon juice. Stir in the teaspoon of baking soda. Give the mixture a taste and add in some sugar if
