Usually it's modelled by an exponential, rather than a vector.
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
The zero vector is both parallel and perpendicular to any other vector. V.0 = 0 means zero vector is perpendicular to V and Vx0 = 0 means zero vector is parallel to V.
Resultant vector or effective vector
Vector spaces can be formed of vector subspaces.
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
Radioactivity affect the water molecules. Radioactivity makes it harmful
What other sort of radioactivity is there?
For example natural and artificial radioactivity.
Radioactivity can be induced in ordinary matter by artificial transmutation.
You cannot measure radioactivity in litres
Radioactivity in Japan is about 15,000 terabecquerels.
Human + A lot of radioactivity = Dead
Artifical radioactivity
no but she built the knowleage of radioactivity.
You need radioactivity, for many things such as x-rays.
NO. Henri Becquerel was the discoverer of radioactivity.
Radioactivity has nothing to do with diffusion.
