How do you find centroid? Centroid of a Triangle Definition: For a two-dimensional shape “triangle,” the centroid is obtained by the intersection of its medians. The centroid of a triangle = ((x1+x2+x3)/3, (y1+y2+y3)/3) To find the x-coordinates of G: To find the y-coordinates of G: Try This: Centroid Calculator. How do you find the centroid […]

How does a photon interacts with matter? In a pair-production interaction, the photon interacts with the nucleus in such a manner that its energy is converted into matter. The interaction produces a pair of particles, an electron and a positively charged positron. These two particles have the same mass, each equivalent to a rest mass […]

Why is energy released in a fission reaction? Fission is the splitting of heavy nuclei (such as uranium) – in two smaller nuclei. This process needs less energy to ‘bind’ them together – so energy is released. The larger nuclei again needs less energy to hold it together – so energy is released. What is […]

What is the purpose of stick drop test? This test uses the known properties of gravity to determine how long it takes a person to respond to the dropping of an object by measuring how far the object can falls before being caught. How do I improve my ruler drop test? Ruler drop test Person […]
