? Combustion is a chemical change in matter, being caused by reactions with oxygen and some type of burnable material.
Supporting combustion is a chemical property
The answer would be:
Pulling a trailer up a hill
Here is why:
In physics, work is computed by the formula:
W = Fd or F(cosΘ)d
Where: F = Force applied on the object
d =displacement
So in order for work to be done, the object needs to be displaced. In the case of the trailer, the trailer is being pulled and it is travelling in the direction of the force applied.
The other options the object is not displaced. Even if you exert a force, if the displacement remains the same, then it will always be zero, so the force times displacement will be 0, hence no work is done.
Answer:
The Minimum wavelength is 
The Maximum wavelength is
Explanation:
From the question we are told that
The energy range is 
Considering 
When a single photon is transferred to to an electron the energy obtained can be calculated as follows

This energy is mathematically represented as

Here h is the Planck's constant with value of 
c is the speed of light with value of
Substituting values and making
the subject of the formula
