2.(That is, there must be a physical space to store a value.) For instance, you can assign a constantvalue to a variable (A = 4;), but you cannot assign anything to constantvalue—it cannot be an lvalue. (You can’t say 4 = A;.)
6.Orbital velocities in spiral galaxies, instead of declining with increasing distance from the galactic center, flatten out to a constantvalue, as predicted by MOND.
7.An electronic circuit which holds the output of a circuit at some constantvalue. A clamp is used in some data sets to hold receiver output constant and avoid troublesome noise interference when no data signals are being received.
