Do X-Ray exist?
They definitely do exist. X-rays are a type of electromagnetic radiation (like visible light, radio waves, microwaves, etc) with a wavelength of 10 - 0.01 nanometers, or about 100 times shorter than visible light on average. X-rays can be generated by machines used in medicine, and are also part of background radiation in the cosmos. Over exposure can be very dangerous; many governments set limits on the amount of x-rays that an individual can safety be exposed to in a given time period. Happy Science : )
Why converting a base class pointer to a derived class pointer is consider dangerous by the compiler?
There are two methods of casting one type to another: static casting and dynamic casting (both of which apply to pointers and references to objects). Statically casting a derived class to a base class is typesafe as the base class is guaranteed to exist if the derived class exists. However, static casting from a base class to a derived class is always considered dangerous as the conversion is not typesafe. Dynamic casting exists to cater for this scenario, however it is only possible when the base class is polymorphic (thus ensuring the required runtime information is available). If the conversion is not possible, the return value is NULL. However, it is considered bad programming practice to dynamically cast from a base class to a derived class. If the base class is polymorphic (which it must be), there is NEVER any need to dynamically cast between types. Virtual methods ensure correct behaviour. Whenever you are forced to dynamically cast from a base class to a derived class, consider redesigning the base class interface instead, as it is a clear sign of bad design. It is not dangerous, however; only static casting from a base class to a derived class is considered dangerous.
Why TEM modes does not exist in wave guides?
Arif Ullah khan utman kheel this is because for conductor E parallel is zero this means that the surface of the wave guide is at equipotential and this potential follow the laplace equation .it means that there is no maxima and minima inside the wave guide . this means that the electric field inside zero . hence the TEM do not exist in wave guide only TE and TM can be exist . if we place some conductor in the wave guide then the conductor inside will not be equipotential and the TEM waves can be exist . like in Coaxial cables
How can genetic engineering help to solve food crisis?
By providing food crops that have greater yield and can exist in a range of conditions. or By creating a food supply for all people
What is the difference between an inventor and a discoverer?
An inventor creates something new that did not exist before. A discoverer finds something that did exist but nobody had found it.
Could humans survive unaided on jupiter in regards to the presence of water there?
No. Jupiter has no solid surface on which bodies of water might exist, though clouds of liquid water may exist below the visible cloud surface. In addition to lacking a solid surface, Jupiter has an unbreathable atmosphere and the gravity is more than twice as strong as it is on Earth.
What are the defects that occur in a baby with Spina Bifida after birth?
None of the defects occur after birth, they all develop in the womb. They continue to exist for the entire life of the person, of course.
Does atheism believe in casting out demons or evil spirits?

Can frictionless surface exist?
No.
Is Venus too cold for water to exist on its surface?
No. Venus is far too hot for water to exist on its surface.
What is the element of casting that don't exist in short stories or novels?
One element of casting that doesn't exist in short stories or novels is the physical embodiment of characters through actors. Casting involves selecting individuals to physically portray characters, which is unique to film and television adaptations. This process can add a visual element to characters that is not present in written works.
Is vaccuum visible?
A vacuum is not visible, as it is an absence of matter. Matter must exist to be seen, and so a vacuum cannot be seen.
What planet is too cold for liquid water to exist on the surface.?
Mars is a planet that is too cold for liquid water to exist on its surface. Almost the entire surface of Mars is covered in ice.
It is to hot for liquid water to exist?
It is too cold for liquid water to exist on the surface
Does the technology exist to see an atom?
No there is no technology to make individual atoms visible
Why goldsilverand cooper were discovered?
Because they exist in nature as metals and are very visible.
Does a Country or Bluegrass version exist of the popular Christian song Who Am I by Casting Crowns?
Yes, there is a Bluegrass version of Who Am I. One version is on a CD titled "Casting Crowns Bluegrass Tribute". There are others as well, this is one example.
