Which one win the race- solid and hollow cylinder

Consider two cylinders of different metals, different diameters, and different in mass now take example

One is a copper metal and another one is aluminium

Now Consider copper as mass M1 and aluminium as M2 and and also consider that mass of the copper is greater than the mass of the aluminium

And here diameters also varies now place them on a sliding plane and remove the barrier both cylinders will Start rolling in a pure rolling manner now which one wins the race

You might think the copper with heavier mass wins the race but actually not, neither one wins both will reach the point at same time now again repeat the task with material of different diameter and length

The results is neither one wins the race

Finally take an one hollow material and another one solid material now did the same race here the result change hollow one lose the game

The reason is kinetic energy (1/2 mv2) and Geometry of the material plays a major role in energy it causes the solid to win the race.

How to calculate age of tree using ring without cutting

How to calculate age of tree using ring without cutting The rings in the trees are used to calculating the age of the trees and tells what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life. The color and width of tree rings can provide snapshots of past climate conditions. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years Calculating the age of the tree without cutting The age of the tree can be calculated without cutting the tree with the help of an instrument called Increment borer this instrument is bored into the tree up to the centre and collect t

Light speed is possible

Light speed is possible Yeah ,light speed is possible but want for an enormous amount of energy.Okay ,how much energy? It's approximately equal to the Big Bang's energy.You must know about one truth,but this one is scientists theory and no one in this universe is not able to prove practically.Because of our life span is very less compared to universe and suppose you want to proof that you must create very powerful engine.This engine having equal amount of big bang's energy.And start the engine ,You set origin (0,0) from your location and you will set your engine balance your origin point.After starting your engine the earth will move more than 3 lakh kilometers and also whole galaxy in just one second.But you will not submit your results to earth ,it goes continuously more than light speed.Yeah we are travel more than light speed and we are the example of achieve light speed.When Big Bang happens it releases enormous amount of energy ,this energy expands our entire mat

Why computer mouse have red LED light?

Why computer mouse have red LED light? A computer mouse is a optical mouse, which uses a light source, typically a light-emiting-diode, and a light detector, such as an array of photodiodes, to detect movement relative to a surface.Variations of the optiocal mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.But why red is mostly used, simple as red diodes are inexpensive and silicon photodetectors are very sensitive to red light.
