In this section, include a summary of how your Rube Goldberg device design works from start to finish to complete a task. Your Rube Goldberg device design must include at least three energy transformations.

Example 1: The ball will have potential energy at the top of the mountain, when the ball falls the ball will have kinetic energy .

Example 2: When it falls it will have potential energy, then cut the scissors, therefore when it gets to the wood it will have kinetic energy.

Example 3: When it slings shot it will fall into kinetic energy, then stop and stay at potential energy.

Explanation: Example 1: when the video first begin "the ball had potential energy and when the ball swung and hit it that potential energy turned into kinetic energy."

Example 2: As the video moves on and the two pillars crashed down it caused another ball to move, at first the "ball had potential energy because it was not moving then when the ramp went down it caused the ball to gain kinetic energy."

Example 3: At the end of the video the ball push down a row of wooden blocks then lead to it hitting a "bowling ball across the finish line even though the ball moved slowly and not far it still came from potential energy into kinetic energy."

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

answer: (431,2)
