Answer:
Infinite distance; all objects in the universe.
Explanation:
In physics, there are four fundamental interactions, and the fundamental interactions include strong force, electromagnetic force, weak force and gravitational force. These forces governs how objects or particles interact and how certain particles decay.
With respect to their relative strengths, the strong force is regarded as the most powerful, followed by the electromagnetic force, the weak force, and the gravitational force.
Gravitational force and electromagnetic force operates at infinite distance. Gravitational force acts between all objects of the universe, no matter the distance/how far the body are apart.
Answer: work is the pressure acting through the change in volume
Explanation:
In the same way that work is defined as force operating over a distance, work is the pressure acting through the change in volume. Pressure is comparable to force in pressure–volume work, while volume is analogous to distance in the classic definition of work.
Answer:
Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
Answer:
im pretty sure its b
Note that when the acceleration is negative — on the interval [0, 2) — that means that the velocity is decreasing. When the acceleration is positive — on the interval (2, 4] — the velocity is increasing. Speeding up and slowing down.
