A bimetallic strip (brass/steel), which is straight at room temperature, will be immersed in boiling water and allowed to equilibrate. I will then remove the strip and quickly place it on a piece of graph paper to measure the deflection of the end, i. e. how far the end is away from the original line, measured perpendicular to the original line. The bimetallic strip is 222 mm long. The thickness was measured to be 0.036”.
Predict how far the end will deflect, to the nearest half millimeter.

the force on the thing and the distance the force moves the thing

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

b. a lightning bug, plug of grass, and a worm
