PLEASE HELP Describe how the Rube Goldberg device design that you created follows the law of conservation of energy. Be sure to include both parts of the law of conservation of energy in your description.

I don't know i am sry

The following answer was written by KaptainEasy, a user using this app, so credit goes to them. But I figured that it would be ok to send you their answer from a different post if I said that it hasn't been answered by me. Goodluck on future exams/assignments : )

"Rube Goldberg machines, follows the “law of conservation of energy”, this machine uses a chain reaction to complete a simple task in different manner,  

In this machine, a various instant kinetic energy is transferred into potential energy and vice-versa , so the total energy remain conserved. Thus Rube Goldberg machines follows law of conservation of energy.

In this machine when marble rolls down from top it has kinetic energy. Then the marble hits and falls into a plastic cup, its kinetic energy is transferred into potential energy that lifts the soda can.Then potential energy is changed into kinetic energy. When the marble make contact with the next marble, then its kinetic energy is transferred to other marble. When marble falls its gravitational energy is released. This gravitational energy built up into kinetic energy, which was transferred to the domino. Each domino passes its energy to the next in a chain reaction until the last one sets off the mousetrap. As the mousetrap is set off, it discharges all of its stored potential energy which pulls back the scissors. The string tying down the balloon is cut, freeing the balloon and its potential energy stored."  

learn it on the intertant so you can solve

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
