Answer:
The right option is option E. None of the answer choices given are totally correct.
Explanation:
All insulators normally have an equal amount of positive and negative charges distributed on their surface.
The amber rod (an insulator) is called negative because after the coming together with fur (another insulator), the amber rod rubs off electrons from the fur onto itself and has an overall more negatively charged particles than positively charged particles on its surface.
The fur in turn becomes positive because it has more positive charges than negative on its surface.
So, the convention allows the now rubbed off amber rod to be called negative.
So, it is evident that none of the answer choices are totally correct, the right answer is more of a mix of some of the answer choices and more!
Hope this helps!!
This shows observational learning, as Ian is following what others are doing and what others are encouraged to do. This is in contrast to other kinds of learning like classical and operant conditioning, where people learn based on associations of an event and a result (rather than based on what other people are doing).
The current is sent through transformers to increase the voltage to push the power long distances. The electrical charge goes through high-voltage transmission lines that stretch across the country. The electricity travels through wires inside the walls to the outlets and switches all over your house.
Answer:
A)
2. very cool but very luminous
6. found in the upper right of the H-R diagram
B)
1. The majority of stars in our galaxy
5. the Sun, for example
7. a very hot and very luminous star
C)
3. not much larger in radius than Earth
4. very hot but very dim
Explanation:
Main-sequence stars :
Main-sequence stars are the star which having hydrogen in the core and also having stable inward and outward force.
White dwarfs :
This is also a star like the sun .The temperature of these type of star above 100,000 Kelvin.The mass of White dwarfs is less than the sun but slightly more than earth.
Red giant or supergiant stars :
This is the biggest star in the universe.When a star does not having hydrogen fuel in the core then Red giant or supergiant stars are formed.
A) 2 ,6
B) 1 , 5 ,7
C) 3 ,4
Answer:
3.) 12
Explanation:
an atomic number is 11 which means this atom will have 11 protons. the atomic mass is 23 which also means 23-11 is 12 neurons.
