Answer:
work is the answer because work is said to be done if an object is displaced by the application of force
A a wire, a wire is connected between the positive and negative ends of the eletrical energy source and connects all the components in between.
Evidence for the particle nature of light are not: 1. refraction, 2. many colors of light, 3. diffraction. These are all phenomenon that support wave theory of light. Evidence for particle nature of light is photoelectric effect. Because it was discovered that you need discrete energies of light to eject electrons from a metal surface and not continuous as the wave theory of light suggests.
force of gravitation between two different masses is given by
![F = \frac{Gm_1m_2}{r^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7BGm_1m_2%7D%7Br%5E2%7D)
here in first case we will have
![F_1 = \frac{G(1kg)(2kg)}{(1m)^2}](https://tex.z-dn.net/?f=F_1%20%3D%20%5Cfrac%7BG%281kg%29%282kg%29%7D%7B%281m%29%5E2%7D)
Newton
another case we have
![F_2 = \frac{G(1kg)(2kg)}{(2m)^2}](https://tex.z-dn.net/?f=F_2%20%3D%20%5Cfrac%7BG%281kg%29%282kg%29%7D%7B%282m%29%5E2%7D)
Newton
another case we have
![F_3 =\frac{G(2kg)(2kg)}{(1m)^2}](https://tex.z-dn.net/?f=F_3%20%3D%5Cfrac%7BG%282kg%29%282kg%29%7D%7B%281m%29%5E2%7D)
Newton
so the force will be maximum in last case when two 2 kg mass is placed at 1 m distance and minimum force is in second case when 1kg and 2kg mass is placed at 2 m distance
