Sound intensity is inversely proportional to the square of the distance
from the source.
-- Increase the distance from the source by 10 times.
-- Sound intensity decreases to 1/102 = 1/100 .
-- 10 log ( 1/100 ) = -20 dB
-- 100 dB - 20 dB = 80 dB
Yes, that's correct. Weber's law states that the just noticeable difference (JND) between two stimuli is proportional to the intensity of the initial stimulus. This means that the difference needed to perceive a change in stimulus intensity remains constant regardless of the initial intensity level.

The initial force needed for a machine to do work is determined by the resistance of the load being moved, the mechanical advantage of the machine, and any friction or inefficiencies present in the system. This force is typically calculated based on the work to be done and the distance over which the force must be applied.
In a car the maximum acceleration (deceleration) caused by breaks is about 1 g. Thus the faster the initial speed, then the greater the time AND distance needed to come to a stop will be required.
To effectively incorporate interval training into your workout routine, alternate between periods of high-intensity exercise and low-intensity recovery. Start with a warm-up, then perform short bursts of intense exercise followed by periods of rest or lower intensity. Gradually increase the intensity and duration of the high-intensity intervals as you build endurance. Be sure to listen to your body, stay hydrated, and consult with a fitness professional if needed.

An increase in energy will generally result in an increase in speed, which will in turn increase the stopping distance required for a vehicle to come to a complete stop. This is because the kinetic energy of a moving vehicle is directly linked to its speed, so the greater the energy, the greater the speed, and consequently the greater the stopping distance needed. Conversely, a decrease in energy will result in a decrease in speed and stopping distance.
The input force would increase as the height of the ramp increased. It wouldn't matter the distance. Ask me another one.
Increasing the distance from the fulcrum to the load will increase the effort needed to lift the load. This is because when the load is farther from the fulcrum, a greater force is required to overcome the increased resistance due to the longer lever arm. Conversely, decreasing the distance from the fulcrum to the load will require less effort to lift the load.
The distance needed to stop also increases.
