Answer:
Static electricity is the result of an imbalance between negative and positive charges in an object. ... When two materials are in contact, electrons may move from one material to the other, which leaves an excess of positive charge on one material, and an equal negative charge on the other.
Answer:
Diffusion and Dispersion.
Explanation:
The two processes that took place in the given experiment are Diffusion and Dispersion.
When a crystal of potassium magnet is added placed in the bottom of a beaker which contains cold water, after 5 minutes the particles of potassium magnet will diffuse with water through diffusion process and the colour of water turns purple.
After few hours, the colour of solution goes light purple because the tiny particles which were diffused earlier will dispersed in the water and the particles will spread and make the solution lighter in colour.
Hence, the two processes are Diffusion and Dispersion.
The correct answers from the choices are:
a. Reduce inflammation locally
b. Antagonize H1 receptors
c. May be administered orally
<span>d. Are systemically distributed
</span><span>Antihistamines are drugs that are H1 antagonists or blockers, may be administered orally, are distributed systemically, and do not directly reduce nasal congestion.</span>
Darwin's Theory of Evolution by Natural Selection.
Darwin divided this theory into multiple parts but overall it fits into Darwin's Theory of Evolution by Natural Selection, so that would be your answer.
In case you're wondering about the others:
1. Organisms produce more offspring than actually survive.
2. Every organism must struggle to survive.
3. There is variation within a species.
4. Some variations allow members of a species to survive and reproduce better than others.
5. Organisms that survive and reproduce pass their traits to their offspring, and the helpful traits gradually appear in more and more of the population.
(these are brief explanations, they go into more detail)
Good luck!
The resistance of the wire is dependent on temperature, diameter and nature of the material.
<h3>What is resistance?</h3>
The term resistance refers to the opposition offered to the flow of current in a circuit. The resistance is obtained form Ohm's law which states that;
V = IR
Where;
V = voltage
I = current
R = resistance
Hence, the resistance is dependent on;
- temperature
- diameter
- material
