When using a series circuit to connect four small light bulbs, which statement is MOST accurate?A) If one bulb fails, the other three can remain operational.
B) The current passing through each bulb is the same.
C) By adding more light bulbs in the series, it will draw less current from the power source.
Eliminate
D) As more light bulbs are added in series, the brightness of the bulbs will stay the same.

Answers

Answer 1

Answer:

Answer:

The correct answer is option b) "The current passing through each bulb is the same."

Explanation:

A series circuit is one where there is only one path for the current, from the power supply source through all the elements of the circuit, to return again to the source.

Because the current flowing through it only has one way to go, the same amount of current will be supplied at the same intensity throughout the circuit.

The equivalent or total resistance of the circuit is the sum of the resistances that compose it and will be greater than the greater of the resistances of the circuit. This means that as we add terminals (the devices connected to the power grid, which receive the current and transform it into another type of energy), the resistance increases.

Taking into account the definitions and characteristics above, the correct answer is option b) "The current passing through each bulb is the same."

Answer 2

Answer:

It's B.

The current passing through each bulb is the same. As you add more light bulbs, the current will decrease in each, but it will always be the same current passing through each one.

Why do fewer kinds of organism live in desert than in forest biome

Answers

Hi there!

Great question!

Fewer kinds of organisms live in deserts than forests because they have special adaptions to their own home... and there are a few, loooong examples below for you to read.

ENJOY!

Camels have a water storage in their humps on their back, so they can go a long time without drinking any water. They have tan fur color to blend in with the sand for predators. They have a short-haired coat on most of their body because of the hot sun, but because deserts can get very cold at night (almost dropping temps below 0), they have thicker fur on their humps and neck. If they were moved to the forest biome, they would take a long time to adapt to their new home.

Next example can be a wolf. A wolf can live in the forest because it has adapted over time to make a wolf, well, a wolf. It has thick fur for keeping it warm at night and in wintertime. A wolf has such a particular diet, that if it lived in a desert, it wouldn't find much food. In the desert, there are snakes and scorpions and bugs, whereas the forest has the deer and caribou to eat.

See, so its pretty simple. Basically, animals live where they live for a reason. If you just moved them to somewhere else in the world, and this could be anywhere, they would take a loooong time to adapt to their new homes.

* A great example of animal adaptation over time is the spirit bear. A spirit bear is a black bear, with white fur, and they aren't albinos. Its a hair color that is very rare, and according to scientific studies, the ratio to spirit bears and black bears in the forest is 1:10. They have developed white fur overtime because the black bears are much darker than the spirit bears, and fish underwater, their source of food, can see them right above the water before the bear dives for a meal. The Spirit bear, however, has a better time catching the fish underwater because it has white fur, not allowing the fish to see her above. Then she dives in for the catch and is successful! *

9. Which of the following human body systems work together for support, protection, and movement? A. the respiratory system and cardiovascular system B. the skeletal system and muscular system C. the skeletal system and integumentary system D. the integumentary system and digestive system

Answers

The Human body system that work together for support, protection and movement is ; ( B ) The skeletal system and muscular system

The skeletal system provides support for every other system present in the human body and it also gives the organism its shape as well. while the muscular system protects the vital internal organs from external shocks.

Both Skeletal and muscular system provide movement, support and protection for the Human body because without any of these the human body cannot make movements or support itself efficiently.

Hence we can conclude that The Human body system that work together for support, protection and movement is The skeletal system and muscular system.

When atoms form a bond, it is usually because each atom acquires a more stable arrangement of electrons in its electron shells. What is the best description of this arrangement of electrons?

A.
All shells have the same number of electrons.

B.
The inner shells are empty.

C.
The outer shell is completely full.

D.
All shells are half full.

Answers

C. Usually when an atom loses or gains an electron, it is because it is trying to satisfy the Octet Rule. The Octet Rule states that an atom is at its stablest when it has 8 valence electrons (two in helium's case)

If you look on the periodic table, elements on the left (Alkaline Metals) are the most reactive because they only have one valence electron (or electron in the outer shell). Elements on the right (Noble Gases) are the least reactive because they have a full outer shell of 8 valence electrons.

Later on you will find that as stability decreases as you go down the periodic table but that is a discussion for a different time.

the answer is C.The outer shell is completely full.

Why does an object traveling in a circle at a constant speed always accelerate ?

Answers

Because "acceleration" doesn't mean "speeding up". It means any change
in the speed or direction of motion.

An airplane speeding up, a bicycle slowing down, and a car going around a curve, are all doing accelerated motion.

A circle has no straight parts, so an object traveling in a circle is always changing
its direction. That means accelerated motion, even if its speed doesn't change..

I'm not sure but I believe it is momentum, when an object keeps moving and keeps Its speed
