metal... hahaha

>> No.1104540

in general, in terms of hardness factor, only items of equal or greater hardness can cut into a given substance.

If you were asking if the car would scratch the wall, then yes, both cars would scratch each other.

If they would both break or shatter 9assuming they are simply one huge "hardest metal", and not joined by an expoxy/etc....then it depends on the integrity of the substance, and how much energy they are moving with.

Two bricks wont shatter if they lightly bump each other, but if you throw them together hard enough, they will overcome their integrity, and break.

So, even if it takes the energy of a supernova, there WILL be some force that can cause these two objects to break when they hit each other.

Which item breaks more? it depends on the shape the item item is in (aka, in the direction of the colliding force, which object has more "material" behind the point of impact, to spread out the force?)

mirrors aren't perfect reflectors. and very little of the light travels in a perfectly parallel path.

some light is absorbed by the mirrors.

So, if you *could* move that 2nd mirror in, all you might see is a small bright area in the direct middle of the mirror, but if would soon fade away.

You need an initial charge to turn on the light bulb. Assume the photovoltaic cell has enough to light the the bulb for 2 seconds. It would initially light the bulb or 2 seconds, but the mechanism of the photovoltaic cell isn't a perfect conversion-- only a fraction of the emitted light is abosrbed and processed into a current.

if you attached a voltmeter, you would see a drop in current very rapidly in the photovoltaic cell.

you must input more energy than you currently are expending to travel at your current speed. Since nothing can go faster than the speed of light, the best you could do is make the ball travel with you at the same speed. no amount of energy could make the ball travel faster than you.

No you wouldn't, you would only see the scattered light, which would be a relatively small proportion, and therefore quite dim.

Not sure but If you drove a car made of wall into 400 mph at diamond I think you could safely say it would have a yield of around 40 megatons.

true. only the light leaving would be seen. you might see a very brief "haze" of light as the non-parallel beams escape.

you wont see the beam in the middle, but it will soon lose energy and disappear

This really is a more interesting question than the typical trolling implies. Most people usually get hung up on the words "close the door faster than the speed of light", but it's not so odd a concept.. one doesn't necessarily have to move the door at FTL speeds, one simply has to close the door in a shorter amount of time than the light takes to reflect back to the entrance. Given a big enough box in space, this is possible.

The question, then, is how long would the light "last"? Surely some would be absorbed by the material lining the box and lost as thermal energy.. but how quickly would this take place? Would there indeed be a brief flash of light if someone opened the door several moments later?

maybe if you stomped the box very, VERY fast.

even the best reflective materials we have, complete absorbtion and net change -> heat would occur so very fast. less than 1 millisecond, I'd say.

if I spit while riding a bike, the spit accelerates relative to the speed of the bike, and I can't feel any difference. Are you saying that spitting in 28 km/h takes the same amount of energy as spitting in 10 km/h?
