In this machine when the ball rolls down it has kinetic that then its gravitational energy is released. This gravitational energy built up into kinetic energy, which was transferred to the wooden block. Then the ball hits the first wooden block, its kinetic energy is transferred into more kinetic energy that makes the chain reaction. When the block and dominoes make contact with the next block or domino, then its kinetic energy is transferred to other block or domino. Each domino passes its energy to the next in a chain reaction until the last one just falls. As the last domino falls, it discharges all of its stored potential energy. PLS HALP THE HOMEWORK IS 01.03 SCIENCE 2

Yes you ate right.

Explanation:

When the ball hits the block its kinetic is transfered to the block and as t he block hits other block it is transfered into it in this way energy is transfered. Moreover some energy is lost due to friction as a heat and sound. But overall energy change remains same.

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
