Hi! I'd just please like to know the most efficient way to conduct my experiment. See, my research question is "for what angle is horizontal speed the fastest?" We all know that the steeper a hill is, the faster an object accelerates. Obviously a 90 degree angle won't do much. I will try to...

Have you ever tried to eat honey that has been in the refrigerator - hopeless huh? Both the viscosity and the density of honey change with temperature and water content and I'm told the viscosity and temperature follow a inverse cube relationship. Honey is mostly sugar (glucose/fructose and...

I mean, since Qatar is rich in oil, electricity is mainly generated from it.

I was thinking of constructing my own thermoelectric generator and test it on the weather conditions here in Qatar. And afterwards, based on whatever results I get, conclude on whether or not the use of thermoelectricity is an appropriate alternative for Qatar?

Uhm, I haven't exactly figured out the details yet. But I thought that it'd be interesting to know if whether or not the use of thermoelectric generators would be an ideal thing.

Hi, guys! So my school has a science fair coming up, and I've decided to do an experimental research on this topic: Determination of thermoelectric characteristics in the ambient environment of Qatar. I'll be using peltier tiles...? I live in Doha, Qatar. Thoughts? Thanks :)

Hmmm, yes, but... It does have a lot to do with the country's fuel economy, doesn't it? I'm slowly realizing that there may be a lot of flaws to that research question. I thought of another one... You know, just so I'd have a lot to propose to my supervisor. - Determination of thermoelectric...

Also, regarding Mr. Huffman's suggestion, if it's "hypothetical", am I then also basing it on hypothetical data? Because I just realized that if no machine is 100% efficient, then what's the purpose of proceeding with the experiment? :/

Fuel efficiency and fuel economy... Wow. Those are really good ones. I haven't exactly thought of the parameters yet as I am still on the verge of proposing the project to my supervisor. I was initially going to propose another project before, but I stumbled upon a reading that a country such as...

Thanks so much for the critique! I'll most likely stick to Mr. Huffman's suggestion of quantifying the performance of a hypothetical 100% efficient solar powered car as it could be supported experimentally. It's not too hard nor too simple as well. If you've got any other suggestions or...

Hi! I was also thinking, maybe measuring the effectiveness of Solar Energy as the primary power source of a city?

As I am currently residing in Doha, Qatar, I've decided to base my mini-thesis on Solar energy. And although I haven't got it finalized yet, I'm thinking of investigating the efficiency of solar powered cars. I could build a toy car and input solar-powered batteries as opposed to another toy...

How do i measure the speed of the rotation of the sun using that experimental set-up?

Hi, everyone. I am researching on a variety of different Physics topics to conduct my Extended Essay on. I was thinking, what if I made a spectrograph to measure the sun's light? Surely I'd be able to get emission and absorption lines which will more or less portray something about the sun's...

Ohhh. That explains a lot. Thanks :) Have you got suggestions on how I'd be able to do this experimentally as opposed to the one suggested above?
