If electromagnetic forces were somehow increased equally, would it take more energy to excite atoms?

Specifically would an object with said increased electromagnetic bonds etc. exhibit appearances of being colder than they actually were due to the increased energy required to excite them?

What is the fastest possible human powered object

I contend that the fastest human powered object would be the smallest thing that could be engineered by humans  fired by a linear accelerator powered by chris hoy on a bike but how fast could that theoretically go? And what could be faster?

Can an ant survive being microwaved for two minutes? I (accidentally) microwaved an ant for 2 minutes today, and it lived!

After microwaving a plate of food for two minutes, when I removed the plate, I noticed a living, normal and healthy ant on the bottom of the plate.  Assuming I did not pick up the ant post microwaving -- something I am almost certain I did not -- how is it possible for an ant to survive being microwaved for two minutes?  Chiton exoskeleton?  Weird surface area effect?  Ants are from space a la Fred Hoyle? ;)

Any help is appreciated.

What is the sound produced by a radio set to AM when a flash camera, say, is charged beside it?

When I charged a flash camera beside a radio set to AM, I noticed a series of sounds produced, similar to that of the harmonics of a sliding square waveform with frequencies above 16000 Hz. How do they interfere and what part of the camera generates radio waves?

Hair-raiser 2

We took the single span cable car from Lake Skalnaté, at 1751m above sea level, to Lomnický štít which, at 2634m above seal level, is the second highest peak in the Tatra mountains.

The peak was covered in cloud with little wind. The air was highly charged with static, I could feel what hair I have standing up and my wife got shocks from the metal handrails that surround the narrow ridge.

Suddenly I felt a slight but definite slap on my head. I was taken by surprise and was wondering if I had been hit by a bird when, perhaps two seconds later, there was a crack of thunder. I had seen no flash when I felt the slap, but had been looking down at the time.

My wife did not notice the effect but felt it prior to a second thunder clap, I did not feel the effect the second time, the lightning was again unseen.

The sensation definitely felt like a physical contact and I firmly link it to the lightning.

What was it we experienced and how could it precede the sound?

 

 

I avoided holding the handrails, which were earthed, after hearing the thunder. Was I correct in assuming this would be safer than holding them?

 

Would the steel cable  to the ground over 883m below not have been very attractive to lightening and how would this have been protected against at the winding gear?

Regards

Hal
