what are the first 3 rules that Newton made??
Answer:
Newton's Laws of Motion
Explanation:
1st- Inertia- every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
2nd- The second law states that the greater the mass of an object, the more force it will take to accelerate the object
3rd- action reaction- If the forces are equal in opposite directions, the object will not move. The forces cancel each other out so that the acceleration is zero. If one force acting in one direction is greater than the force acting in the opposite direction, the object will move.

In your own words explain the difference between potential energy and kinetic energy. Give an example of how one can be transformed into the other.
Explanation:
When an object is at rest, the body is said to possess potential energy. In another case, when the object is in motion, then it is said to possess kinetic energy. Potential energy tends to affect the object within the environment if and only when it gets transformed to other kinds of energy.
The magma inside of a volcano slowly cooled into rock. Over time, wind and water wore away the weaker rock surrounding it. The landform left at Earth's surface is made of
A. igneous rock
B. metamorphic rock
C. sedimentary rock

Answer:
the correct answer is igneous rock
Igneous rock is formed through the cooling and solidification of magma or lava.

If a 3.0 picogram (pg) sample of curium-245 has a half-life of 8500 years, which conclusion can be drawn?
A: The curium-245 sample must have an age of at least 8500 years.
B: The curium-245 sample must have an age of less than 8500 years.
C: The curium-245 sample will have a mass of about 6.0 pg after 8500 years.
D: The curium-245 sample will have a mass of about 1.5 pg after 8500 years.
Answer:
its A
Explanation:
If a 3.0 (pg) sample of curium-245 has a half-life of 8500 years, then the conclusion which can be drawn is the curium-245 sample will have a mass of about 1.5 pg after 8500 years
What is half life time?Half life time is that time after which initial concentration of reactant becomes half of the initial.
Given that initial concentration of curium-245 = 3pg
After half life time concentration of curium-245 = 1.5pg
The curium-245 sample must have an age of at least 8500 years is wrong as given time is the half life time.The curium-245 sample must have an age of less than 8500 years is wrong as given time is the half life time.The curium-245 sample will have a mass of about 6.0 pg after 8500 years is alo wrong as left sample shold be half of the initial.Hence, the curium-245 sample will have a mass of about 1.5 pg after 8500 years is the conclusion.

Which diagram represents an electrically neutral atom?
Answer:
D
Explanation:
I hope this right, I'm sorry if it's not.
For an atom to be neutral, it has to have the same amount of protons and electrons. Because protons and electrons have opposite charges, when there is an equal amount of them they balance each other out
The diagram that represents an electrically neutral atom is:
Option D
What is an electrically neutral atom?Whenever a molecule has an equivalent number of electrons and protons, it has an equivalent number of -ve electric charges (the electrons) and +ve electric charges (the protons). The all-out electric charge of the 0 is thusly zero and the particle is supposed to be unbiased.
Thus, option D is correct.

What is the greenhouse effect?
Answer:
the greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.

4. Greta passed a comb through her hair several times. She then placed the comb next to a stream of water flowing from a faucet. Greta observed the stream of water bend toward the comb.
How did passing a comb through her hair allow the comb to bend the stream of water?
A) by making the comb more absorbent
B) by giving the comb an electrical charge
C) by increasing the thermal energy of the comb
D) by breaking some of the chemical bonds in the comb
the correct answer is B
Passing a comb through hair allows the comb to bend the stream of water by giving the comb an electrical charge. Therefore, option (B) is correct.
What is static electricity?Static electricity can be defined as the accumulation of an electrical charge in an object. The electrical charge will develop when two objects are rubbed against each other.
When the things are rubbed together, some electrons jump from one object to the other. Since electrons are negatively charged, the object becomes positively charged as it loses the electrons.
The comb attracts the stream of water as the charge on the comb attracts the molecules of water. The stream bends toward the comb because the molecules in the stream can be moved easily. The water molecules are polarized molecules and their effect is stronger than with dust.
Therefore, the stream of water is attracted toward the positively charged comb and it bends.

The word igneous comes from the Latin word for fire. However, the name is inaccurate. The rocks are not created with flames. Instead, they are created when magma cools and hardens. Magma is hot molten rock found deep in the earth. Igneous rock is either intrusive or extrusive. It is intrusive when it forms inside the earth's crust. It is extrusive when it is formed above the earth's surface.
Select the sentence from the passage that supports the idea that temperature is an important factor in the formation of igneous rock.
Question 10 options:

The word igneous comes from the Latin word for fire.
Magma is hot molten rock found deep in the earth.
It is intrusive when it forms inside the earth's crust.
Answer:
Instead, they are created when magma cools and hardens —> the temperature contributes as the magma would be at extreme heat while it need a cooler temperature to harden and mold
