1. Explain how the model of the atom has changed over time.
2. How was the atomic theory able to be changed over time?
3. Does the term indivisible still accurately describe the atom? Explain.
Task# 2: The Structure of Atoms
1. Use the items that your teacher gives you to build a model of an atom. Assign one color to represent each subatomic particle of your atom.
Color Subatomic Particle Charge
2. Draw your model and be sure to label your diagram with the subatomic particle names to show you where you placed them.
3. Since subatomic particles are matter they have mass. Compare the masses of the subatomic particles. Where is the majority of an atom’s mass located?

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
