my room home and light clarity sunlight https://postimg.cc/gallery/77kF8C1?fbclid=IwAR14R3aIp7fBRMr0XNubJaxv8KXwIGJWwTk-V34v_E1BMubDu62nryGzAmE

I have a PS2 Slim 90000 and its case is ABS plastic and it has rubber parts, this device is located on a wooden table, the lights with UV in my house and the sunlight coming into the house will dry out, crack and damage the ABS plastic and the rubber of this device? my house uses LED bulb

Doubt about humidity and oxidation, I don't live near the beach and I keep electronic devices inside cardboard boxes and in an open anti-static bag, an air dehumidifying device that uses a compressor sucks moisture only from the air or sucks moisture inside the boxes and do bags?

I think the question is more about the lifetime of the device, not how long it holds a charge.

Googled [ shelf life of electrolytic capacitor ] ... but was confused by the results as they seem to imply pretty much any device I have (that has such caps) that's older than three years should begin to fail! Must be missing something.

yes

electrolytic capacitors of electronic devices can remain unused for how long so that they do not depolarize and lose capacitance?

a teacher told me that UV is not a high penetration wave, is that true? to pass through materials and cardboard it needs to be a high frequency wave

In your opinion, is the cardboard in these boxes shown in the photos good or bad to protect the interior from light and UV?

I was confused because some people where I live said that UV and light penetrated the cardboard but you say that then I don't trust you who are experts

i don't have aluminum to wrap the cardboard box i don't know the type of UV that penetrates the cardboard but would you recommend that i keep or throw the cardboard in the trash?

do the cardboard boxes shown block or not block UV and light?

I keep them inside a black box and the box inside the cardboard box my doubt now is the black casebox will heat the DVD discs reducing their durability? will the black cardboard box also heat up the disks that are inside it? all of them are in my closet the cardboard box on top of the closet and the black box and shoe inside the closet

this image that I posted the rays cross penetrate the cardboard these rays is UV?

The DVD I own is MDisc and conventional DVD, I keep them inside a black box and the box inside the cardboard box my doubt now is the black casebox will heat the DVD discs reducing their durability? will the black cardboard box also heat up the disks that are inside it? all of them are in my closet the cardboard box on top of the closet and the black box and shoe inside the closet

this image that I posted the rays cross penetrate the cardboard these rays is UV?

all the boxes are kept closed I have the same boxes as in the pictures but I have doubts if it is protected from light and UV because I saw this:

Mechanically produced CDs and DVDs are unaffected by normal levels of sunlight.

Ones you 'write' yourself (recordable and re-recordable) work on a different (chemical) principle which is light sensitive.
Some brands are worse than others.
So for these yes light protection is necessary.
Cardboard is better than paper  - the thicker the better.

my DVD discs are recordable or virgin and I had this doubt if the cardboard protects or the light and UV penetrates through the cardboard

Does the cardboard material used in boxes protect from light and UV? I keep objects sensitive to light and UV inside these boxes example: DVD discs and plastics 

In my case of hammer and electric drill what is the resonance and sound waves compared to the screaming glass bowl and airplane?

I know that some people break bowls with the scream and planes break glass, in these two cases is it only resonance? and in my case is it compared to these two cases?

Of course I can.

But you did not reply to my last explanation or question.

I need the replies to find the best way to answer and help you.

 

 yes i read your post and i use tradutor

the answers you said is no, but can you explain it? drill and hammer

Does electric drill noise damage objects in the room through sound waves?

I just want an explanation as to why the use and hammering of wood and metal inside a closed room will not cause sound waves and crack objects by the sound wave noise

is this a question of chemistry or physics? the bags are all inside the box but they are crumpled folded and between the bags is the dvd case, if these bags hold any moisture that gets deposited in them through the air then this can be dangerous because the moisture sweat from the bags will pass to the dvds and the cardboard box what is her behavior? does it suck moisture and make you sweat?

If your ear drum is not damaged, neither will your DVDs !!!

to cause any damage what would have to happen? doesn't the sound of hammering cause it? frequency or intensity or volume of sound?

my ear is not bad but the other objects I don't know

Yes, to the first part of your question.; sound ( pressure pulses ) will be generated in all directions.
No, to the second part; the sound waves will damage nothing.

The only plausible scenario is the hammer slipping out of your hand, and hitting your disc case.

what is the explanation for the sound waves produced by the hammer not to damage anything through air and sound displacement?
