As you well know, soap bubbles exhibit wonderful iridescent color patterns. their origin is similar to the effect that makes oil slicks colorful (see explanation in muller's book): the reflection of light at the two sides of the very thin soap film. look up what the word "iridescence" actually means and explain, why this effect occurs for soap films. if you feel a little schematie picture might your argument, feel free to supply one. (hint: interference! )

explanation:

small = small current large mag large current

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
