The correct answer is
<span>B) UV waves are higher frequency and carry more energy.
In fact, UV waves have higher frequency than visible light. For comparison, visible light has frequency in the range 430-770 THz (</span>
)<span>, while ultraviolets (UV) have frequency higher than these values (at the order of 1 PHz, </span>
).
The energy of electromagnetic radiation is proportional to its frequency, according to the equation
where h is the Planck constant and f is the frequency. We see that the higher the frequency, the greater the energy, so UV waves carry more energy than visible light.
Answer:
1.5 × J
Explanation:
The initial force, which in this case is the external force is equal to 15N. Logically, when 150 Joules of work is done upon that system the overall energy will increase by that very same amount of work applied on the system which is 150 J.

Answer:
Pascal's principle, also called Pascal's law, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container
