A negative of a vector represents the direction opposite to the reference direction. It means that the magnitude of two vectors are same but they are opposite in direction.

For example, if A and B are two vectors that have equal magnitude but opposite in direction, then vector A is negative of vector B.

Suicidal bag also known as lysosome is a cell organelle which are sphere shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules including the useful cells and materials that can derail the functioning of the cell . It mostly occurs in ageing, dead and diseased cells.

Lysosome is called as suicidal bag because it helps in the self-destruction of its cell, tissue or organs by releasing the lysosomal enzymes caused by rupturing of their...

According to the Heisenberg Uncertainty Principle, it is impossible to determine the exact spin of an electron at any given moment. The Uncertainty Principle states that the more precisely we know the position of a particle, the less precisely we can know its momentum, and vice versa. Spin is a form of intrinsic angular momentum, which means it does not correspond to any specific position in space, and therefore cannot be measured precisely at the same time as its position.

However, while we...
