We have all experienced the force of gravity. It is what happens to you when you jump up into the air. Disappointingly, we tend to fall right back down to the ground. But what if we could switch gravity off? What will happen if the gravity vanishes? Buckey, an astronomer, says that...
What happens if a dynamometer gives incorrect readings? Incorrect readings can lead to misguided assessments, potentially leading to engine designs that do not meet performance or safety standards. 1 Are there different types of brakes? Yes, there are various types of brakes including disc brakes, ...
whatever you want, and because you can get away with whatever you want. Thanks to human weakness, this is all possible, possible because of the Gap between you and the truth, the gap that is created at the expense of those millions of innocent lives. This is what happens if the ...
The light emitted by a pulsar carries information about these objects and what is happening inside them. That means pulsars give scientists information about the physics of neutron stars, which are the densest material in the universe (with the exception of whatever happens to matter inside a blac...

I think the worst that happens is you can lose your park location, maybe wang your camera out a bit. Most mounts and telescopes are more rugged than you would think. And they have a generous amount of compensation for Human Error.
A lock-up is when a driver brakes so hard that one or more wheels starts to under-rotate, or stops rotating altogether. This often leads to a puff of white smoke from the tyres, and can result in flat spots that force a driver to pit for fresh rubber. ...
When operating a refrigerator, it is the noise that occurs when a stopping compressor increases the RPM quickly. Hmm~, beep~ Continuously Wind noise generated by the fan motor rotating. - There is a change of rotation speed depending on the operating conditions (set temperature, inside...
Mechanically, a clutch is needed anytime there are two rotating shafts that need to spin at different speeds. Clutches can be quite complicated and can be found in all kinds if electromechanical devices. In the case of a lawnmower, the clutch resembles a fairly simple on/off switch.Both the...
As this happens, nuclear fusion in the outer shell of the star continues and this causes these outer layers to "puff out." These shed outer layers cool around the still collapsing core, which, if it is massive enough, will begin a new round of nuclear fusion, forging helium into heavier...
