A recent study found that electrons that have energies between 3.45 eV and 19.9 eV can cause breaks in a DNA molecule even though they do not ionize the molecule. If a single photon were to transfer its energy to a single electron, what range of light wavelengths could cause DNA breaks?minimum wavelength?

maximum wavelength?

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

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
