Answer:
Halving the wavelength doubles the frequency and, thus, doubles the energy of the incident photons. This doubles the energy given to each electron, nearly doubling its kinetic energy after it is free from the metal.

Explanation:
<em>A scientist can contribute to the formation of a theory in a particular subject by conducting research along the line of that subject.</em>
Conducting research requires the formation of a hypothesis and testing the hypothesis by conducting a relevant experiment during which data are gathered, analyzed, and interpreted in order to falsify or accept the hypothesis.
A good experiment must be replicate-able. When the same experiment is repeated by different independent researchers and the same conclusion is arrived at, this could potentially lead to the formation of a theory.
<u>Hence, a scientist can contribute to the formation of a theory by conducting an experiment with replicability in order to test a hypothesis.</u>
The answer is A.
All risks have the potential to cause death as a driver. You can harm yourself, others, or both when you take risks on the road. No one can predict what could happen next and when you drive, you do not only need to consider what you would do. You have to understand that behavior of other drivers and pedestrians is unpredictable.
