Objects too far away from the Sun do not orbit it. Explain why this occurs.
Answer:
The Sun's gravitational pull is not as strong as objects get farther away
Explanation:
Answer:
The answer would probably be gravitational pull
Explanation:
The farther an object is from the sun and the slower it will orbit the sun. If an object is closer from an other star than to the sun, or the field of attraction of this star is stronger than the one of the sun, this object will not orbit the sun at all.

what does the world sunlight map tell you about how much sunlight Australia gets compared to Brazil.
Answer:
well i think that Australia has more sunlight than Brazil based on the map and the colors and numbers that show on the bottom also Australia has more direct normal irradiance and has more solar coverage than other continents checks out and the sun hits Australia more cause Australia is facing the sun more i think cause for example Antarctica is very cold cause that place is not facing the sun as much as Africa, Australia and other places.

Amy has a mass of 30 kg, and she is riding a skateboard traveling 5 meters per second.
What is her momentum?
5 kg⋅m/s
6 kg⋅m/s
30 kg⋅m/s
150 kg⋅m/s
Answer:
A is correct
Explanation:
Momentum is the product of mass and velocity of the moving object. The momentum of Amy weighing 30 Kg riding with 5 m/s is 150 Kg m/s.
What is momentum?Momentum is a physical quantity measuring the product of mass and velocity of a body. There are both linear momentum and angular momentum. Angular momentum is the momentum associated with a rotating body.
Momentum of a body increases with increase in mass and velocity.
The mass of the girl is given 30 Kg riding with a velocity of 5 m/s. Thus her momentum can be calculated as:
p = m v
= 30 Kg × 5 m/s
= 150 kg m/s.
Therefore, the momentum of Amy is 150 Kg m/s.

Non-metals are found where on the periodic table?
A. Everywhere
B. Center
C. Lower left side
D. Upper right side
A. physical
D. Upper right
Answer:
1.) A, a physical change
2.) D, Upper right side
Explanation:
1.) Changing states does not atomically change the chemical build up of any object. Water is still water whether as liquid H2O, ice, or water vapor. Since it is only changing how an object looks and not the chemically make up, melting and freezing constitutes as physical changes
2.) Non-metals are elements that do no share the traits and characteristics of a metal. Most non-metals classify as a gas. This includes : helium, hydrogen, oxygen, carbon, nitrogen, and sulfur just to name a few.
Where are all these elements found on the table? The right sides of the periodic table.

Redox reaction is the oxidation of iron, which forms iron oxide, also known as rust. This reaction can be symbolized with the following equation: 2Fe + 3O2 forms Fe2O3. Notice the iron atoms and oxygen molecules combine to form a new compound, which makes this reaction a chemical change.
A car engine uses the combustion of fuel to move a system of gears that
move its wheels. Not all of the fuel's energy is transferred to the wheels.
Which two transformations happen to the rest of the energy?
I A. It is transformed into sound energy.
O B. It is transformed into thermal energy.
I c. It is transformed into chemical energy.
D. It is transformed into nuclear energy.
E. It is transformed into kinetic energy.
Answer:
A and B
Explanation:
When a car engine uses the combustion of fuel to move a system of gears that move its wheels, the fuel's energy is transferred to the wheels and the rest of the energy: is transformed into sound energy and thermal energy. So, option (A) and (B) are correct.
What is law of conservation of energy?Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present. The law of energy conservation is adhered to by all energy forms.
In a nutshell, the law of conservation of energy asserts that the system's total energy is conserved in closed systems, or systems that are separated from their environment.
When car engine uses the combustion of fuel to move a system of gears that move its wheels, maximum of its energy transformed into kinetic energy and rest of energy is dissipated in a form of sound energy and thermal energy. So, option (A) and (B) are correct.

what is santa's average speed when visiting houses if he visits 800 million houses over 48 hours?
Well, "speed" normally = (total distance covered) / (time to cover the distance).
In this case, we don't know the total distance that Santa has traveled, so the question can be answered only if we're willing to consider some other meaning of "speed".
Maybe we could say that in this case, "speed" means the average rate at which he visits houses. Then ...
Speed of visits = (total houses visited) / (time to visit them).
Speed of visits = (800 million houses) / (48 hours)
Speed of visits = 16.67 million houses per hour.
That's 277.8 thousand houses per minute
That's 4,630 houses per second

Read this excerpt from Through the Looking-Glass by Lewis Carroll.
“That would never do, I'm sure,” said Alice: “the governess would never think of excusing me lessons for that. If she couldn't remember my name, she'd call me ‘Miss!’ as the servants do.”
“Well, if she said ‘Miss,’ and didn't say anything more,” the Gnat remarked, “of course you'd miss your lessons. That's a joke. I wish YOU had made it.”
“Why do you wish I had made it?” Alice asked. “It's a very bad one.”
But the Gnat only sighed deeply, while two large tears came rolling down its cheeks.
“You shouldn't make jokes,” Alice said, “if it makes you so unhappy.”
Then came another of those melancholy little sighs, and this time the poor Gnat really seemed to have sighed itself away, for, when Alice looked up, there was nothing whatever to be seen on the twig, and, as she was getting quite chilly with sitting still so long, she got up and walked on.
Question:
How does Lewis Carroll’s use of opposites appear in this excerpt?
Answers:
1#. Alice says that her governess would never excuse her from her lessons, even if she 2#. did not have a name.
3#. The gnat jokes that Alice would have to miss her lessons if the governess called her “Miss.”
4#. The gnat makes jokes, but they seem to cause him unhappiness rather than joy.
5#. The gnat disappears after he lets out one last sigh and Alice looks up at the tree.
