I am required to ask questions as part of my physics assignment at school. Im in Yr 11 physics btw. If some people can please answer these that would be great. Before anyone says i should know some of these or that i could find out by surfing the internet, i know that i canm but none the less i would stil be required to ask questions to a person/s about physics. Thanks in advance. 1)Why does the colour black heat faster than white? 2)How and why are rainbows formed? 3)Why does a diamond sparkle? 4)why does water cool down so much slower than it heats up? 5)What are Newton's three laws? 6)Why can a person lie on a bed of nails and not be injured? 7)What is a Black hole? 8)When you look into water why do objects appear to be in a different spot than if you were looking from underwater? 9)Is there any truth in the statement "Red is the fastest color"? 10)What are potential and kinetic energy?
