Answer:
- <em><u>Step 2 (the slow step).</u></em>
Explanation:
The rate-determining step is always the slow step of a mechanism.
That is so, because it is the slow step which limits the reaction.
Imaging that for assembling a toy you have process of three steps:
- 1. order ten pieces, which you can do in 1 minute: meaning that you can order order the pieces for 60/1 = 60 toys in 1 hour.
- 2. glue the pieces and hold the toy until the glue hardens, which takes 1 hour: meaning finishingh 1 toy in 1 hour.
- 3. pack the toy, which takes 2 minutes: meaning that you can pack 60/2 = 30 toys in one hour.
The time to glue and hold one toy until the glue hardens determines that you can assemble 1 toy in 1 hour and not 60 toys or 30 toys.
Thus, the step that determines the rate at which the reaction happens is the slowest step: step 2.
It is reflected ir transmitted depending on what the material is. The color that something appears is actually the color that it reflects or transmits and not the color that it absorbs. I hope this helps.

Answer:
Currents in the aluminum sheet set up a magnetic field that opposes the oscillations
Explanation:
It has been stated in the question that the aluminum sheet hangs from one of the arms and passes between the poles of the magnet and causes the magnetic field to decay rapidly. In the absence of this magnetic breaking, the oscillation may continue for a long time.
As the aluminum hangs from one of the sheets and passes between the poles of the magnet, the magnetic flux linked to the sheet changes and emf is induced in the sheet according to Lenz law. As a result of this induced emf, eddy currents are developed on the plate. The Eddy currents opposes the magnetic force on the aluminum sheets. This opposes the oscillation of the aluminum sheet and causes it to come to rest.
