One is human usage. This is because everyday humans use the Earths natural resources (coal,gas,oil). This is anything from cooking food on a stove to driving a car. We already know that these resources are running out and they are finite. Therefore as the demand for them increases, more and more is being used everyday and the availability is decreasing at a faster and faster rate every single day.

34kurt

Answer:

d=4.67ft from the weaker source

Explanation:

The illumination of an object by a light source is directly proportional to the strength of the source and inversely proportional to the square of the distance from the source:

Illumination=k*S/d^{2}   first source

Illumination=k*4S/(14-d)^{2}   second source (stronger)

If the illumination is the same for the two sources:

k*S/d^{2}=k*(4S)/(14-d)^{2}

We solve to find d:

2d=14-d

d=14/3=4.67ft from the weaker source
