The sun is made ofgas and plasma. Most of the gas — 92% — is hydrogen. If the sun were smaller, it would just be a huge ball of hydrogen akin toJupiter. According to NASA Space Place, the hydrogen in the sun's core is held together by a lot ofgravityresulting in high pressure...
An example of an air cooled GPU is the MSI Gaming X Trio variant of the Nvidia RTX 3080 Ti (what’s Ti?). This model uses three TORX 4.0 85 mm fans, which have double-ball bearings and blades that are linked (in pairs) on the outer ring. Image-Credit:MSI These fans cool the 2....
Here’s the strange part, as you move further away from the Sun into its atmosphere, the temperature rises again. Above the surface is the chromosphere, where temperatures rise back up to 20,000 degrees Celsius. Then there is the corona, the Sun’s outer atmosphere. The corona as a wispy...
As the outer layers expand, the radius of the star will increase and it will become a red giant. The radius of the red giant sun will be just beyond Earth's orbit. At some point after this, the core will become hot enough to cause the helium to fuse into carbon. When the helium ...
In the cockpit, there is also a device called the associated control unit, which provides pre-amplification for audio going to the CVR. The four microphones are place in the pilot's headset, co-pilot's headset, headset of a third crew member (if there is a third crew member) and near...
A Montrealers' favorite motto could very well be "life is short, summer's shorter." While they cram in as much fun as they can when the weather is fine, Montrealers have also figured out a way to play all year-round. As cold as it may get, Montrealers will shrug off Old Man ...
Using a simple motor-driven fan and a heating element, hair dryers blow hot air over wet hair to accelerate water evaporation. The heating element is usually a bare, coiled wire that heats up due to electrical resistance. The fan then blows air over this element, warming it before it exits...
The core of the matter is this: Even a clear sky isn't empty. Our atmosphere is a massive fluid layer, and the right application of physics makes it possible for humans to traverse it. In this article, we'll walk through the basic principles of aviation and the various forces at work...
Putting hot leftovers directly into the refrigerator raises the temperature inside, so it has to work harder -- and burn more energy -- to keep foods cool. Allow your leftovers to sit at room temperature for a while before putting them into the refrigerator. Check the rubber seal on your ...
