It has turned out to be difficult to find a reproducible definition otherwise - basically, one that has sufficient precision, accuracy and stability. However, that will probably change soon; this is a known problem, and people are working on finding a good alternative. Check the Wikipedia article on "Proposed redefinition of SI base units" - it is expected that a new definition (in which the kilogram will probably be defined on the basis of the Planck constant, as well as on the second and the meter) will be accepted in 2018.
A standing wave can occur only at specific frequencies that are called natural frequencies.
No, it cannot. In the case of an object moving in the free space (no forces acting on the object) the energy consists of only the kinetic energy which is proportional to squared momentum. Thus, if the object has a momentum it has an energy to. Basically an object possesses some energy in any kind of time, and it might happen that the energy is zero. It doesn't mean that it has no energy. It means that the object has energy equals zero (which is not the same).
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
Natural selection requires that individuals in a population are
Yes, forces do all of these things. A force changes the velocity of an object, and is the only thing that can change the velocity of an object.
There are many artificial satellites - thousands of them. The Moon, however, is the only natural object that is large enough to be noticed.
Silk is the only natural fiber classified as a filament fiber. It is produced by silkworms and consists of long, continuous strands that can be woven into luxurious fabric.
The only natural object we know of that does that is the earth's moon.
Physical security measures refers to such things as locked doors or padlocks, which require a physical object in the form of a key to open them, rather than a password, which consists only of information, rather than a physical object.
Any natural satellite that revolves around a planet. Our Moon is Earth's only natural satellite and the fifth largest satellite in the Solar SystemThe moon refers to the natural satellite of the earth that is usually visible at night.
There really is no problem created from not using standard measurements. The only problem that could arise is confusion between people or miscalculations when substituting in formulas.
A linear meter is the same as a standard meter, it is a way of emphasizing that only one dimension of an object is being described
When the only force on an object is the force of gravity,we say that the object is in "free fall".
The boolean operation that keeps only the volume common to two solid objects is the intersection operation. This operation creates a new object that consists only of the overlapping region of the original objects.
Using a standard keyboard in standard temperament, look for the three black keys. The white key immediately to the left of this grouping is F.
