Quantization of electric charge means that electric charge exists only in discrete amounts, not as a continuous value. In nature, all electric charges are integer multiples of the elementary charge, e e e, which is approximately 1.602×10−19 1.602 \times 10^{-19} ...
Ballistic missiles are rocket-powered weapons that follow a high, arcing trajectory to deliver a payload—often nuclear, chemical, or conventional warheads—to a target. After an initial powered flight phase, they coast through the atmosphere or space, following a predictable, parabolic path ...
