Use LF or lower HF frequencies (rather than UHF or VHF), proper SWR tuning of antennas, radio amplification.
This is a sonography related term. Increased through-transmission, also known as enhancement, is an increased brightness of echoes deep to low-attenuating structures.
distance = rate x time the distance is increased or decreased in direct proportion to the rate or time. If the rate doubles the distance doubles in given time; If the time doubles the distance doubles at a given rate.
When the speed of a vehicle doubles, the braking distance is increased by approximately four times. This is because the braking distance is directly proportional to the square of the speed.

If a simple machine provides an increased output force, then the output distance will decrease. This is due to the principle of work conservation, where input work equals output work. As the force increases, the distance through which the force acts decreases proportionally to maintain the balance.
In a power transmission there is a need for step up and step down the voltage for a certain distance. So we cant use dc for a particular distance.AnswerD.C. transmission is used for long-range extra-high voltage transmission, for under-sea high-voltage transmission, and for international 'links'. The equipment for achieving these voltages is far more complicated/expensive compared with transformers, making short distance d.c. transmission uneconomical.
High voltage.

The size of the force decreases. It is inversely proportional to the square of the distance.
