To calculate this we will use the light equation:
λ
We have Frequency
.
We know that speed of light in vacuum is
.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:
<span>
</span>
<span>
λ
</span>⇒ λ
⇒ λ
⇒ <span>λ</span>
<em>Energy transformation</em>, also known as <em>energy conversion</em>, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (Ex: Moving a heavy object from one place to another) On top of that, being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it CANNOT be created or destroyed.
When it comes to transforming electrical energy to mechanical energy, A generator converts mechanical energy into electrical energy, while a motor does the opposite. A motor converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
P.S - After doing some searching, I have found something that should help you, if what I said is confusing or not helpful to you at all. This website has helped me on many occasions and is a very helpful and valuable tool.

Well it couldnt be an animal cell becuase animal cells dont have cell walls. And plant cells have a cell membrane not a plasma membrane so it should be a prokaryotic cell.
It penetrates the skin and can cause mutations.
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- <u>Claim</u>: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- <u>Evidence</u>: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- <u>Reasoning</u>: <u>cohesion</u> in water depends on the force of attraction between H₂O molecules, <u>adhesion</u> is the capacity of H₂O molecules to join other different molecules and —together with <u>surface tension</u>— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.
