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.

A. physical change
B. nuclear change
C. chemical change
QUESTION 2
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.
Four forces are exerted on each of the two objects shown below:
Which object will move in the up direction?
A : Object A but not Object B
B: Object B but not Object A
C: Both Object A and Object B
D: Neither Object A nor Object B
Answer: Object A but not Object B.
Explanation:
Answer:
A. Object A but not B
Explanation:
Because object A has the most force pulling up, 6 newtons. It has weaker forces pulling on all other sides but the upward force is the strongest
Object b will not go up because it has just as much pulling down on it as it does pulling up. Since there's 3 newtons of force pulling up and 3 pulling down it cancels out and does not move

Why is the principle of periodic motion used in pendulum and quartz clocks?
[please answer fast I will mark you as the brainliest :-) ]
Answer:
A pendulum of given length always takes the same time to complete one oscillation. The time period of a pendulum of given length is constant. Thus, the periodic motion of pendulum has been used to make pendulum clocks for measuring time.

I believe it's light from the flashlight carried energy, and
there was energy in the toy that was activated by the light
A solar powered toy moved when you shines a flashlight on it. this is explained by:
light from the flashlight carried energy.energy from the flashlight was absorbed by the toy.What is solar energy?Solar energy is the radiation that the Sun emits that has the ability to create heat, trigger chemical reactions, or create electricity. The total solar energy incident on Earth is far greater than the global energy needs at the moment and in the future. This highly diffused source might potentially provide all of the energy required in the future if properly harnessed.
As the solar powered toy moved when you shines a flashlight on it, it absorbed the energy from the flashlight and light from the flashlight carried energy.

What will happen when you slide the sponges in different directions?
Transform boundary
is the answer from stemscopes
The sponges will contract when there is a slide of sponges in different directions.
What are the sponges?Sponges are called as the members of the phylum Porifera. This is a basic animal group and the diploblasts' sibling. They are multicellular creatures with pores and channels that let water to move through their bodies, which are made of jelly-like mesohyl sandwiched between two thin layers of cells.
Sea sponges were among the earliest animal groups to form on Earth, but new chemical evidence puts their appearance 120 million years earlier than previously assumed, according to New Scientist.
According to the research, it is found that When there is a sliding of sponges in opposite directions, the sponges will compress. As water filters through the porous shell of a sponge, it develops motion, obtains food and oxygen, and expel waste.
Therefore, Flagella, microscopic hairlike structures inside the sponge, produce currents that filter germs out of the sponge's cells and trap food within them.

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.

Explanation:
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

A piece of unknown metal with mass 68.6 g is heated to an initial temperature of 100 °C and dropped into 42 g of water (with an initial temperature of 20 °C) in a calorimeter. The final temperature of the system is 52.1°C. The specific heat of water is 4.184 J/g*⁰C. What is the specific heat of the metal?Identify a potential source of error that may have occurred during the calorimetry experiment. Justify your response in two or more complete sentences.
According to the mass of the metal and the temperature it should be under the average heat of water which is 4.184 but also above it, which brings us back to how much it dropped which means that it goes back and going half way.

Student A
An oceanic plate converged with an oceanic plate. Both plates subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
Student B
A continental plate converged with a continental plate. Neither plate subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption which created the mountains.
Student C
An oceanic plate converged with a continental plate. The more dense, continental plate sank below the less dense oceanic plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.
